  • Estimating Distribution of End Prices Using Hierarchical Bayes Model in B2B Luxury Brand Goods Auctions

    Japanese, Scientific journal,

    Auctions have long been used to trade goods that do not have a fixed price. In recent years, with the spread of internet auctions, the number of goods that can be handled at a single auction has increased. The time required to make a bidding decision per product remains the same even when a large number of goods are traded, such as in wholesale. For this reason, a large time is required to determine the valuation in proportion to the number of goods. This causes problems for the auctioneer and the participants. It is difficult for the auctioneer to set the reserve price and for the participants to decide the amount and target of their bids. It is necessary to understand the value of a product and estimate the end price. Since there is no fixed price for a product sold in an auction, we estimate the distribution of end prices instead of point estimation. We focus on B2B luxury brand goods auctions, where the number of goods is large and the bidding decision cost per product is high. We estimate the distribution of successful bids on actual auction data of wristwatches, which have large transaction volumes in the auction. The performance of the proposed method was measured by MAE, RMSE, and MAPE, and was close to that of experts. The proposed method was able to capture the data distribution. Finally, we show that the end price distribution estimation can be used to support both auctioneers and participants in brand-name auctions with a large number of goods.

    Scientific journal, Owing to technological advancements in medicine and nursing, an aging population has emerged in Japan. Consequently, the elderly need extra care and support from their caregivers. This study develops an autonomous forearm-supported walker for users who can handle the walker without any support. The three main functions of the proposed walker include moving with the weight support of the user, assisting the user in walking, and autonomous driving. These functions are expected to assist the patient in walking, hence reducing the burden on the nursing staff. In this study, we experimented on the degree of support in straight-line walking using the walking support function of the proposed walker. The effect of the walking support function was confirmed by measuring the muscle activity of five muscles of the subject’s lower limbs. In addition, we confirmed the accuracy of the autonomous driving function by checking the results of the self-position estimation during 90 turns and forward movement. Additionally, we conducted a route driving experiment that confirmed the possibility of driving without a significant deviation from the set route.

    Japanese, The evaluation function for an imperfect information game is always hard to define but has a significant impact on the playing strength of a program. Deep learning has made great achievements in several recent years, and already exceeded the level of top human players in perfect information games such as AlphaGo. Predicting opponents moves and hidden states is important in imperfect information games. This paper describes a model on building a Mahjong artificial intelligence with deep learning method and supervised learning theory. Four deep neural network for discarding and predicting opponents' waiting, waiting tiles and point changes are combined into one model and performs good during games. With improved feature engineering, our accuracies on validation data of these networks reach higher than Dr. Mizukami and Professor Tsuruoka's network.

    English, Scientific journal, This project revolves around the combination of different state-of-the-art concepts to create balloon robots which can be used for entertainment purposes. The goal is having multiple robots perform a choreographed flight on preset paths to make use of the “dead space” over the crowd of an event, either as part of the show or displaying information and advertisements. As the balloon is flying on a defined trajectory, a tracking system for its position is needed. For this purpose, several infrared cameras monitor the position of a marker attached to the balloon. The main challenge is overcoming the instabilities of the system to ensure a smooth and precise flight, resulting from the balloons structure: the balloon is filled with helium to counteract the forces of gravity and, therefore, minimize the work needed to keep its momentum. Finding a way to achieve this optimization and the precision mentioned beforehand is the task that we will present and solve in this paper.

    Japanese, Many travel surveys have been carried out in many tourist destinations to investigate tourist's needs. However, traditional survey methods can be time and money consuming. Meanwhile, the analysis of the massive and up-to-date travel reviews may be able to provide a low-cost and real-time substitute. There are many tasks before we can develop a method to perform the investigation automatically. This paper will explain the progresses we have made through manual analysis and show the remaining tasks for developing an automated method.

    English, International conference proceedings, Currently, the prediction of fish species and catches is based on the experience of fishermen. Echo sounders can support fisheries; however, they cannot identify fish species. A system for the identification of fish species with machines has not been established. The purpose of this research is to propose a new method for the identification of fish species using echo sounders attached to a set-net. From the results of an experiment, five fish species (yellowtail, salmon, sardine, squid, and juvenile tuna) were identified with an accuracy of 95%.

    English, International conference proceedings, The conventional control method for road-heating systems, which is controlled mainly by snowfall, is the feedforward control. Therefore, the road-heating systems often operate in spite of no snow on the parking lots. In this paper, we introduce the method of feedback control for road-heating systems that detects snow condition on the parking lots, and turns road-heating systems on and off properly. To recognize the snow condition, we adopt images for recognition using convolutional neural networks.

    English, International conference proceedings, The main feature that keeps states and structures stable can be seen in living organisms. This adjusting and adaptive features are called homeostasis. This integrated adaptive feature is achieved by the cooperation of organs in living organisms. Living organisms in nature act dynamically due to this feature. Highly adaptive behavior caused by this feature is also observed in simple living organisms that have no neural circuits such as amoebas. Based on these facts, a method of control to generate homeostasis in robotic systems is proposed by assuming a robot system is an aggregation of oscillators and each parameter in a robot system is allocated to an oscillator. Especially, interaction between two independent robots as oscillator aggregation is focused in this paper.

    English, Scientific journal, Flocking algorithms for a multiagent system are distributed algorithms that only have simple rules for each agent but generate complex formational movement. These algorithms are known as swarm intelligence and are robust and disaster tolerant for most cases. We consider that flocking algorithms that have these characteristics are the way to generate homeostasis in a system. We expect that by making use of this algorithm the system can tune its self-parameters and thus maintain a high performance. First, to apply a flocking algorithm to a system, we extended the flocking algorithm to form an arbitrary lattice for further flexibility. We then applied the extended flocking algorithm to position tracking camera system as an example. (C) 2015 Wiley Periodicals, Inc.

    Japanese, The main feature that keeps states and structures stable can be seen in living organisms. This adjusting and adaptive feature is called homeostasis. This integrated adaptive feature is achieved by the cooperation of organs in living organisms. Living organisms in nature act dynamically due to this feature. Highly adaptive behavior caused by this feature is also observed in simple living organisms that have no neural circuits such as amoebas. In amoeba case, each cell acts as an oscillator and such behavior is explicable as synchronization phenomena of oscillators. Based on these facts, a method of control to generate homeostasis in robotic systems is proposed by assuming a robot system is an aggregation of oscillators in this paper. When a robot system is assumed as an aggregation of oscillators, a robot system tries to keep the value of the specific function that indicate its uncomfortable level small the whole time. To keep such function value small, a robot system stabilize the relationship between oscillators when its value is small and reconstruct the relationship between oscillators when its value is large. This behavior is also explicable as synchronization phenomena of oscillators. A redundant robot arm is made to confirm the effect of this control method to generate homeostatic behaviors in robotic systems.

    English, International conference proceedings, "Traveling Salesman Problem" (TSP) is one of most difficult and important problems in combinatorial optimization on industrial circles. "Local Clustering Organization" (LCO) was developed to solve large-scale TSP high-speed. LCO is reasonable for implementation to general optimization problems, it has a simple framework based on the principle of "Self-Organization Map" (SOM) for TSP. However, LCO has the defect of operation that was easy to be caught in a local minima. This paper will elucidate the LCO behavior and show two improvements to lack of LCO that is necessary to solve large-scale TSPs. First, LCO operator is explained as compared with k-opt method that is a well-known effective operation in TSP. Two improvements are the extension of LCO operator, and the control of "concentrations of search" which computes on a large search-pace effectively. In analysis of LCO and k-opt method, it is proposed "Insert method" (IM) to "Extended LCO" (ELCO) as a new method of 3-opt type. For making a concentration of search, it is proposed the method that 1-tour is divided into sub-tours and bridges for "Sub-tour extract ELCO" (SELCO). The performances of LCO, ELCO and SELCO are analyzed using "usa13509" of TSP instances. The experiment shows the improvement in the accuracy of solutions and the concentration of searches.

    International conference proceedings, Agent Based Model (ABM) is efficient for analysis of various social mechanisms. Recently, there are many studies on massive agent model to explain more complex social phenomena. Then, we aim for implementation of large scale simulation model using Repast HPC toolkit, a platform for massive agent model. In this article, we build "Schelling Segregation Model" for spatial model using geospatial data provided OpenStreetMap, an open source project creating a free editable map. In this model, agents are located continuous space, not grid in original. When an agent is "unhappy" and migrates to new location, it costs agents some simulation time depending on distance between old location and new one. This article reports simulation results using Japanese cities and verification result about execution time.

Such oscillators interact so that the whole system can adapt to the environment. Also, a redundant robot arm is made to confirm the effect of this control method to generate homeostatic behaviors in robotic systems.
  • Statement-based cost estimate for co-utilization of service facilities

    English, Scientific journal, In this paper, we focus on allocating of social service facilities which are operated under the first-comefirst- serve rule. In such facilities, users cannot make a reservation in advance. To reduce congestion, it is desirable to adjust a schedule by communication devices. We propose the user-in-the-loop forecasting with the statement-based cost estimate, and apply to two types of facility allocation models, i.e., the theme park scenario and the highway scenario. The computer experiments show that the proposed estimate caused better results in both scenarios to reduce congestion. In particular, the users in the highway scenario could achieve a near user equilibrium situation without any advance experience of the system. © 2014 Information Processing Society of Japan.

    DISTRIBUTED AUTONOMOUS ROBOTIC SYSTEMS, 104, 247, 258, SPRINGER-VERLAG BERLIN, 2014, [Peer-reviewed]
    English, International conference proceedings, Flocking algorithms for a multi-agent system are distributed algorithms that only have simple rules for each agent but generate complex formational movement. These algorithms are known as swarm intelligence and are robust and disaster tolerant for most cases. We consider that flocking algorithms that have these characteristics are the way to generate homeostasis in a system. We expect that by making use of this algorithm the system can tune its self parameters and thus maintain a high performance. First, to apply a flocking algorithm to a system, we extended the flocking algorithm to form an arbitrary lattice for further flexibility. We then applied the extended flocking algorithm to a position tracking camera system as an example.

  • Observation of synchronization phenomena in structured flocking behavior

    Journal of Advanced Computational Intelligence and Intelligent Informatics, 17, 5, 715, 720, Springer-Verlag, 2013, [Peer-reviewed]
    English, Scientific journal, Flocking algorithms for multi-agent systems are distributed algorithms that generate complex formational movement despite having simple rules for each agent. These algorithms, known as swarmintelligence, are flexible and robust. However, to exploit these features to generate flexible behavior in an autonomous system, greater flexibility is needed. To achieve this, these algorithms are extended to enable arbitrary lattice formation. In addition, extended flocking algorithms can be assumed to be the aggregation of oscillators and observed the behavior of synchronization. It is difficult to explain the behavior of extended flocking algorithms as a consensus problem but, by assuming the flock as the set of oscillators, it can be explained as a synchronization phenomenon.

    2013 IEEE/ASME INTERNATIONAL CONFERENCE ON ADVANCED INTELLIGENT MECHATRONICS (AIM): MECHATRONICS FOR HUMAN WELLBEING, 1591, 1596, IEEE, 2013, [Peer-reviewed]
    English, International conference proceedings, Not only skill but also determination of strategy (choosing a club and a target) is important to improve golf scores. This study aims to optimize a strategy to help golfer's improve their scores. To optimize a strategy, first, we develop a simulation model that determines the drop position of a golf ball probabilistically. The size of a gap between a target and a position at which the ball actually falls changes depending on the skill parameters. Next, expected values of the score are calculated at every spot among the golf course by the Q-learning [9] using the simulation model. Finally, we check the capability to acquire a strategy through simulation that directs action to a golfer agent using optimized Q-tables. Results of the optimization show that when the shot distance of each club is the same but the shot accuracy is not, a club that has a shorter shot distance is more suitable for a golfer with low shot accuracy than a golfer with high shot accuracy. The strategy is optimized in consideration of course layout and golfer's skills.
  • Analyzing the impact of earthquake on tourists' activity: Travel blog mining
    Kayoko H. Murakami, Hidenori Kawamura, Keiji Suzuki
    International Journal of Advancements in Computing Technology, 4, 22, 239, 247, Dec. 2012, [Peer-reviewed]
    English, Scientific journal, An intensive earthquake off the Pacific coast of Tohoku struck the greater east Japan area on March 11, 2011. The earthquake and resulting tsunami directly affected the international inbound tourism, and the number of foreign visitors to Japan suffered a great decline compared to the previous year. One important method by which we can explore how the crisis affected the international inbound tourism is the analysis of word-of-mouth information by foreign visitors. This paper examined text data collected from a major travel blog website from April 2010 to February 2012 and investigated if there were any tendencies that could be found in the tourists' activities before and after the March 11 earthquake. It found that the number of appearances of the term "earthquake" in the blogs was related to the seismic intensity of each earthquake and aftershock. Also, there were differences in the content of nouns in the blogs posted right after the March 11 earthquake. Earthquake-related words appeared with a high TF-IDF value. However, in the blogs of the following months, Japan travel related terms appeared as topic terms in the same manner as in the blogs before the earthquake. This paper suggests that effective and prompt actions need to be taken immediately following a disaster for the reconstruction of the tourism industry.

    English, Scientific journal, Since the 2011 off the Pacific coast of Tohoku Earthquake damaged the major area of eastern Japan on March 11, 2011, the number of foreign visitors has drastically decreased. Japanese government tried to take urgent countermeasures against the loss. They spread the true information that Japan is safe by using media and Word-of-Mouth (WOM) such as influential bloggers. In this study, we investigate what WOM can be found regarding the earthquake through the blogs posted after the disaster. The blogs including earthquake-related words were collected and analyzed. Extracting the target data from the large number of data allows us to qualitatively examine the data. The text mining approach we used in this study includes morphological analysis and topic words analysis with term frequency-inverse document frequency weight. After that, the topic words and the words with high document frequency were used to find collocation of those topic words. As a result, the topic words "safe" and "normal" were found in the March 2011 blogs while they contained many other topic words about earthquake, tsunami, and nuclear crises. Moreover, gradually the number of earthquake-related words disappeared in the blogs and travel-related words appeared as time went by. In addition, we used concordance software to see the context where the topic words are used and found that the blogs written by the foreign visitors could convey true information about the disaster. © 2012 WIT Press.

    English, International conference proceedings, Multi-agent systems have attracted a lot of attention recently. RoboCup Soccer Simulation is treated here as a testbed of such systems. This study aims to facilitate the analysis of team behavior and to clarify the role of different types of team possession in the game results of RoboCup Soccer Simulation. We construct a method of detecting counter attacks, which are one type of team possession, by analyzing the log files of games. To detecting the counter attacks, anisotropy feature and others are introduced. Based on these features, a support vector machine (SVM) based detector was able to achieve a 77% detection rate. The detecting method will be expected to reduce the burden of visually checking log data.

    English, International conference proceedings, Flocking algorithms for a multi-agent system are distributed algorithms that only have simple rules for each agent but generate complex formational movement. These algorithms are known as swarm intelligence and are robust and disaster tolerant for most cases. On the other hand, most of organizations are constructed from smaller groups, we call it subgroup here. It means activities of organization should be determined by its subgroups but flocking algorithm itself does not have such feature. To express this feature, we extend flocking algorithm to be able to contain subgroups of agents. Also we add flocking algorithm the term that indicates the relationship with other subgroups. By this extension, flocking algorithm is be able to form specific shape more flexibly.

    English, Scientific journal, In many e-commerce sites, recommender systems, which provide personalized recommendations from among a large number of items, have recently been introduced. Collaborative filtering is one of the most successful algorithms which provide recommendations using ratings of users on items. There are two approaches: user-based and item-based collaborative filtering. Additionally a unifying method for user-based and item-based collaborative filtering was proposed to improve the recommendation accuracy. The unifying approach uses a constant value as a weight parameter to unify both algorithms. However, because the optimal weight for unifying is actually different depending on the situation, the algorithm should estimate an appropriate weight dynamically, and should use it. In this research, we first investigate the relationship between recommendation accuracy and the weight parameter. The results show that the optimal weight is different depending on the situation. Second, we propose an approach for estimation of the appropriate weight value based on collected ratings. Then, we discuss the effectiveness of the proposed approach based on both multi-agent simulation and the MovieLens dataset. The results show that the proposed approach can estimate the weight value within an error rate of 0.5% for the optimal weight.

In this paper, for purpose of extending applied area of a humanoid robot, we aimed at the adjustment of a humanoid robot to an underwater area. In other words, it is thought humanoid robot substitutes instead of the person who is working in the sea area and underwater. The property of the action in the water is different compared with the property of the action in the land because the influence of resistance from the wave and buoyancy. Therefore, We think that humanoid robot should change the action between land and water. As a basic research, we examine proposal method to judge whether it is state that robot is floating.

Real ants use pheromone trail to inform each other where food source exists and they effectively reach and forage the food. This sophisticated but simple communication method is useful to design artificial multiagent systems. In this chapter, the evolutionary pheromone communication is proposed on a competitive ant environment model, and we show two patterns of pheromone communication emerged through co-evolutionary process by genetic algorithm. In addition, such communication patterns are investigated with Shannon's entropy. © 2011, IGI Global.

    English, Scientific journal, Blimp robots are an attractive form of small flight robot. because they are maintained aloft by buoyancy, are safe, require little energy and have relatively long flight times. The development of a general-purpose blimp robot research platform allowing modular installation of a variety of hardware and software components will lower the barrier to the creation of new research projects and increase project efficiency. This paper describes the development of such a general-purpose platform and the testing of its suitability for research use. Experiments performed on the platform included: (I) testing of position maintenance capabilities, and changeover from a PID control software module to a learning control module; (2) testing of the ease and effectiveness of exchanging one hardware module (a microphone) for another (a camera); (3) installation of a new hardware module (a microphone) along with an existing module (a camera); (4) testing of addition of functions and performance of a topologic map generation experiment with addition of an ultrasonic sensor. The effectiveness of information fusion combined with a layered software structure was demonstrated in the experiments, indicating that the newly developed platform will be effective in promoting research on blimp robots.

    English, Recent studies have been mainly engaged with movements by 2 or more autonomous robots. Especially, the development of autonomous robots utilized by the industrial manufacture has been advancing. However, the extent of these researches was limited to robots moving in 3 dimensional autonomous robots, such as airplanes or helicopters. On the other hand, regarding studies on small size indoor 3 dimensional blimp robots, characteristics of entertainment robots, indoor surveillance robots, object searching robots in disaster building have been subject to investigation. However, previous studies drew the attention to the difficulties arising when the cooperative behavior of 2 or more autonomous blimp robots is strongly presented depending on changes in the experimental environment, denoting the weak points of these systems. In this paper, 2 small size autonomous blimp robots were used, and basic experiments with time constraints of behavior control were conducted, examining possible coordinated movements of 2 small size autonomous blimp robots, for the purpose of high application achievement of utility. © 2008 The Institute of Electrical Engineers of Japan.

    Japanese, The high-quality service provided by the large-scale tele-communication network constructed in the Internet such as the Gnutella is thought to be achieved by a certain feature network structure. Moreover, a feature structure is assumed to be generated with a certain simple generation rule in another research. This shows that there is a possibility that an effective design approach of the large scale network can be established if the design of the generation rule that generates the optimal structure becomes possible.

    コンピュータソフトウェア, 24, 1, 40, 49, 26 Jan. 2007
    Japanese, When composing networks for a particular purpose, we previously designed optimal topology for that purpose. Many researches so far have focused on designing optimal topology under various conditions given statically. However, in more than a few cases, the network is used during its growing process because it is difficult to construct a whole network at a. burst when considering the construction of an actual network. In this paper, we investigate the feasibility of building an optimal network from the aspects of the optimality and growth elements of topologies, We lead the optimal growing rules for some conditions and take up network models mentioned in the research of complex networks. Experimental results verify that optimal growing rules vary depending on the purposes and conditions of the building of networks and show that the selection of the growing rules makes it possible to build networks optimally.

    English, A blimp robot is attractive as an small flight robot and can float in the air by buoyancy and realize safe to the crash small flight with low energy and can movement for a long time compared with other flight robots with low energy and can movement for a long time compared with other flight robots. However, control of an airplane robot is difficult for the nonlinear characteristic exposed to inertia by the air flow in response to influence. Therefore, the applied research which carried out the maximum use of such in recent years a blimp robot's feature is prosperous. In this paper, we realized development of blimp robot for research which can be used general-purpose by carrying out clue division of the blimp robot body at a unit, and constituting and building for research of blimp robot, and application development.

    English, International conference proceedings, In the network field, various researches have tackled optimizing flow in networks. As shown from previous researches, flow optimality is dependent on the link structure and the routing algorithm that controls the flow. Therefore, a research frame is desirable that optimizes each of them independently but still simultaneously handles both. This study proposes a new scheme called Optimal Flow Network Design Problem (OFNDP) and applies it to a queueing network system; flow optimization is also performed. In the experiment, the number of traffics and each service rate were given to nodes and between each node respectively, and then the flow of each traffic was decided to minimize waiting time by a flow control algorithm based on the dijxtra method. Link structure was also optimized by a genetic algorithm under the constraint of a limited number of links. As a result, sub-optimal flow was obtained with short average waiting time for each traffic.

    Japanese, We focus on a method to calculate the estimated value for a probabilistic model in which each event is defined as a combination of several other independent events. The partially exhaustive investigation Monte Carlo method has been proposed by the authors for such model, and it can show higher performance than simple weighted sampling Monte Carlo method on the condition that the used sample number for estimating is limited. This method divides the event into two parts by a threshold parameter; one is composed by high-probability events, and another is by remaining events. To make this metho...
  • Multiagent analysis for effect of cogeneration spread in an electricity market
    H Kawamura, K Kurumatani, A Ohuchi
    ELECTRICAL ENGINEERING IN JAPAN, 156, 2, 61, 74, SCRIPTA TECHNICA-JOHN WILEY & SONS, Jul. 2006, [Peer-reviewed]
    English, Scientific journal, In this paper, in order to investigate the effect of scenarios in which cogeneration spreads in an electricity market we constructed a multi-agent model of an electricity trading market with power distribution and power generation agents. In this model, we analyzed the effect of reducing power generation surplus facilities on market price formation and stability through computer experiments. As a result of the experimental simulations, the market price was decreased by the increase of sell bids according to the demand reduction by the spread of cogeneration, and by the increase of commercial use of cogeneration facilities, the market price was more economical and stable because such agents supplied more electricity generated by surplus cogeneration. However, if power generation agents reduced the number of power generating facilities when the number of power distribution agents' cogeneration facilities was not significant, the fluctuation of market price grew larger. We confirmed that the spread of cogeneration played an important role in stabilizing market price formation. (C) 2006 Wiley Periodicals, Inc.

Considering that CTLs circulate in vivo and migrate into a tumor tissue, the square is open and CTLs move through the square. By calculating the cellular automaton model, we obtained these results: the growth of a mass of tumor cells surrounded by CTLs; the rejection of tumor cells by CTLs; and an approximate equilibrium between tumor cells and CTLs. Analysis of the results indicates that the attachment between tumor cells and CTLs is important for the rejection of tumor cells by CTLs.

    English, Scientific journal, We are developing an agent and server library referred to as X-Economy, by which we can execute multiagent simulations and network games for financial and economic systems. To this end, we analyzed the characteristics of network games in a financial context and compared them with traditional ones. X-Economy has also provided a new research direction in market micro-structure analysis. We executed several kinds of multiagent simulations for technical traders (indices) and obtained non-trivial suggestions regarding the relationship between the market randomness and the effectiveness of technical indices. For instance, the performance of complex technical indices seemed to deeply depend on the characteristics and nature of a market when a market became complex, i.e. it moved far from the Wiener process.

    English, International conference proceedings, In this paper, we verified the effect of the Distributed Visitors Coordination System in the theme park problem. The system solves the problem caused by time delay between decision-making and emergence of its effect. Its problem can happen generally in the area of congestion information system and causes the oscillation of the queue length in each service facility. In our system, some users register their next destination into a system server, the server estimates future state based on that information. Moreover, we made the exclusive queue for the agents registering next destination in each service facility to stimulate users' registration. According to the computer simulation, even if there were many agents registering excessively, the whole waiting time reduced greatly and the oscillation of queue length in each attraction moderated.

    English, Scientific journal, A distributed visitors coordination system is proposed as an application of a massively multi-agent system. In the system, some agents register their next destination using an information device such as a cellular phone, and this information is used to reduce the effect of the time delay between decision-making and effect-emergence. This delay causes queue lengths to oscillate. However, it is troublesome for agents to continuously register their next destination. To compensate them, exclusive queues are made available to agents registering their next destination. Computer simulation of the theme park problem, showed that when all agents avoid the congestion by registering their next destination, the total waiting time is minimized and queue length oscillation is reduced.

    English, Scientific journal, In an artificial market approach with multi-agent systems, the static equilibrium concept is often used in market systems to approximate continuous market auctions. However, differences between the static equilibrium concept and continuous auctions have not been discussed in the context of an artificial market study. In this paper, we construct an artificial market model with both of them, namely, the Itayose and Zaraba method, and show simple characteristic differences between these methods based on computer simulations. The result indicates the further need to model the market system by studying artificial markets. © Ohmsha, Ltd. 2005.

    Japanese, Balloon robots have attracted attention as new type indoor robots for various applications, e.g., observation, guidance, and amusement flying. A balloon robot can float and move long time in 3-dimensional space by low energy. However, it is difficult to control positioning of a balloon robot because it has great inertia and is easily effected by a little air stream of a conditioner. Positioning control under usual indoor environment is key technology to realize an autonomous balloon robot. In this paper, we develop the indoor-type balloon robot system with a light wireless vision camera. Th...

    IEEJ Transactions on Electronics, Information and Systems, 124, 10, 1930, 1937, The Institute of Electrical Engineers of Japan, 2004, [Peer-reviewed]
    English, Scientific journal, The final goal of this study is to achieve an autonomous indoor blimp robot. While blimp robots are attractive entities moving safely in three dimensional space, they are hard to control autonomously as they are subjected to strong inertial forces and air resistance, and have many nonlinear characteristics. As blimp robots are used not only in vast halls but also in complex buildings with obstacles such as pillars and walls, they need to plan suitable motion for avoiding them. Furthermore, robots need to conserve energy with restricted power supply because they are unable to carry heavy batteries. We have to design an action-value function for planning motion in a blimp robot, considering constraints imposed by these characteristics of an actual robot. In this paper, we designed an action-value function for motion planning based on the potential field method, and evaluated its effectiveness in a simulated environment. © 2004, The Institute of Electrical Engineers of Japan.

    English, Scientific journal, We focus on the simple theme park problem, where there are two attractions and visitor agents which select their destination attraction based on congestion disregarding behavior and congestion avoiding behavior. According to the computer simulation, the result shows that the growth of individual congestion avoiding behavior is not always effective for improving global performance, and this phenomenon is caused by the oscillation of successive selection switching of the same destination by many congestion avoiding agents. Although the model and setting of this paper is simpler than other related works, we consider each phenomenon in those works has the same characteristic based on the ineffectiveness caused by the homogeneity of congestion avoiding behavior and information sharing. © 2004, The Institute of Electrical Engineers of Japan.

    Japanese, Recently, the agent-based simulation approaches have been remarkable to study social, economic, and financial complex systems. In these approaches, a designed agent often has many parameters which characterize itself, and these parameters are dynamically changed according to the ability of learning, evolution, and adaptation. Thus, it is necessary to confirm the methodologies to design, represent, and evaluate agents and interaction ovjectively. To overcome these issues, we found X-Economy Project in which we try to investigate the economic complex systems based on agent-based simulation approaches and propose the methodology for such research style. Namely, we have constructed the simulation platform, called X-Economy System, for artificial economy and artificial market. X-Economy System is expected to become the simulation system like Linux for such type researches. Especially, we have developed some research programs using X-Economy System for gradual investigation of complex economic systems. In this paper, the concept of X-Economy Project, the outline of X-Economy System, some research programs based on X-Economy System, and the aim of researches have been reported.

    English, Scientific journal, Recently, researchers in various fields have shown interest in the behavior of creatures from the viewpoint of adaptiveness and flexibility. Ants, known as social insects, exhibit collective behavior in performing tasks that can not be carried out by an individual ant. In ant colonies. chemical substances, called pheromones, are used as a way to communicate important information on global behavior. For example. ants looking for food lay the way back to their nest with a specific type of pheromone. Other ants can follow the pheromone trail and find their way to baits efficiently. In 1991, Colorni et al. proposed the ant algorithm for Traveling Salesman Problems (TSPs) by using the analogy of such foraging behavior and pheromone communication. In the ant algorithm, there is a colony consisting of many simple ant agents that continuously visit TSP cities with opinions to prefer subtours connecting near cities and they lay strong pheromones. The ants completing their tours lay pheromones of various intensities with passed subtours according to distances. Namely, subtours in TSP tourns that have the possibility of being better tend to have strong pheromones, so the ant agents specify good regions in the search space by using this positive feedback mechanism. In this paper, we propose a multiple ant colonies algorithm that has been extended from the ant algorithm. This algorithm as several ant colonies for solving a TSP, while the original has only a single ant colony. Moreover, two kinds of pheromone effects, positive and negative pheromone effects, are introduced as the colony-level interactions. As a result of colony-level interactions, the colonies can exchange good schemata for solving a problem and can maintain their own variation in the search process. The proposed algorithm shows better performance than the original algorithm with almost the same agent strategy used in both algorithms except for the introduction of colony-level interactions.

    English, Scientific journal, In this paper, we propose a new cooperative search algorithm based on pheromone communication for solving the Vehicle Routing Problems. In this algorithm, multi-agents can partition the problem cooperatively and search partial solutions independently using pheromone communication, which mimics the communication method of real ants. Through some computer experiments the cooperative search of multi-agents is confirmed.

    English, International conference proceedings, In this paper, we propose the collective search algorithm based on pheromone communication for Vehicle Routing Problems. This algorithm is designed using multi-agent system, in which agents autonomously and independently search the partial solution of given problem to decrease their searching load. Pheromone communication imitated from social insects, i.e., real ants and bee, is used as the communication method between agents to emerge the cooperative behavior. Throughout computer experiments, we confirm the effectiveness of proposed algorithm for view point of cooperative behavior.

    The overfishing and depletion of marine resources including tuna have become problems in Japan. Managing to marine resource is necessary to increase catch amount. However, set-net is difficult to separate fish speceis. Therefore, this research used a sonar image obtained by an echo sounder installed in a set-net. We verify of fish species estimation model based on echo sounder image.

    塩治龍三朗, 川村秀憲, 鈴木恵二, IPSJ SIG Notes. ICS, 2015, 2, 1, 8, 23 Feb. 2015
    There are many researches about golf shot relating with distance and accuracy concerning golf. However when aiming to have a better score at golf, it is important not only to practice golf shots but also to correctly know the cause of not being able to get a better score and improving them. Furthermore, there are not many researches about this theme. In this paper, we studied a method to analyze golfers play data to improve skill by using golf simulation and a index called Strokes Gained Stats which evaluate golfers every shot., Information Processing Society of Japan (IPSJ), Japanese

    Hidenori Kawamura, Ryota Ono, Keiji Suzuki, 情報処理学会論文誌, 55, 4, 15 Apr. 2014
    In this paper, we focus on allocating of social service facilities which are operated under the first-come-first-serve rule. In such facilities, users cannot make a reservation in advance. To reduce congestion, it is desirable to adjust a schedule by communication devices. We propose the user-in-the-loop forecasting with the statement-based cost estimate, and apply to two types of facility allocation models, i.e., the theme park scenario and the highway scenario. The computer experiments show that the proposed estimate caused better results in both scenarios to reduce congestion. In particular, the users in the highway scenario could achieve a near user equilibrium situation without any advance experience of the system.------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

  • An Examination of 7 Billion Agent Based Simulation

    Multi-Agent Simulation (MAS) is efficient for analysis of various social mechanisms. Recently, there are many studies on massive agent model to explain more complex social phenomena. Then, we aim for implementation of large scale simulation model using Repast HPC toolkit, a platform for massive agent model. In this article, we build "Schelling Segregation Model" for spatial model using geospatial data provided OpenStreetMap, an open source project creating a free editable map. In this model, agents are located continuous space , not grid in original. When an agent is "unhappy" and migrate to new location, it costs agents some simulation time depending on distance between old location and new one. This article reports simulation results using Japanese cities and verification result about execution time., The Institute of Electronics, Information and Communication Engineers, Japanese

    Flocking algorithm of multi agent system is robust and disaster tolerant even though agents face obstacles or destructed. These algorithms are modeled to generate complex behavior such as flock of birds and fished by simple distributed rules. In this paper, we focus on applying these mechanism to single robot by assuming that the robot is the set of agents. We extend flocking algorithm to be capable of using in single robot and apply it to dog-shaped robot to convey baggage with other robots. In baggage conveying task, robots must deal with complex effects from its environment, the baggage and other robots., The Japan Society of Mechanical Engineers, Japanese

    Effects of body extension and its relationship to learning in robots is not clear even though lots of research have been done. In this paper, to reveal these characteristics, we make simulation robots and attach some rigid bodies to them in order to extend their bodies. Through the interaction in game, extensions increase the average winning percentage of some rule sets. But it does not affect the winning percentage of a specific rule set. Also, each extension has its own collision property and its average collision time is not proportional to the surface area of extensions. We use simulation environment which cause physical effects to robots by using physics engine., The Japan Society of Mechanical Engineers, Japanese

    Recently, multiagent systems has attracted much attention. RoboCup Soccer Simulation is treated as a test bed of these. In real soccer, the analysis of games in terms of team behavior has been studied, however, it has not been done in RoboCup Soccer Simulation. In this study, we aim to facilitate the analysis of the team behavior and to clarify the involvement of the team possession type in result of games in RoboCup Soccer Simulation. In particular, we construct a method of detecting counter attack, one of team possession type and we analyze the log files of games. After considering the feature quantities to detect, we detect counter attack using support vector machine based on four feature quantities. As a result, this detector can detect in 77%. Using this detector will reduce the burden of check the log data in visual., The Japan Society of Mechanical Engineers, Japanese

    The analytic hierarchy process (AHP) proposed by T.L.Saaty is a method for decision making that takes into consideration uncertain situations or multiple evaluation criteria. In AHP, a decision maker gives values of pairwise comparisons between evaluation criteria and alternatives. Therefore the comparisons of all pairs are difficult when evaluating many alternatives. In this study, we propose a new method that named "comparison support method" for evaluating many alternatives when decision maker needs to decide the highest priority alternative. The comparison support method stops pairwise comparisons when only one solution, the highest priority alternative, is found even if all comparisons aren't compared., The Institute of Electronics, Information and Communication Engineers, Japanese

Generally, distance metrics such as Pearson's correlation coefficient are used as the similarity. Although, effectiveness of similarity computation method was widely discussed from various perspectives, there are few considerations of computation methods for optimal similarity in collaborative filtering. In this research, similarity optimization problem were formulated by defining similarities between a active user and the other users as a vector variable. Then, a quasi-optimal solution was obtained and it was compared with Pearson's correlation coefficient.

    We want to work humanoid robot instead of the person in the sea area. In this paper, for purpose extending applied area of humanoid robot, we aim at the adjustment of a humanoid robot to an underwater area. The property of the action in the water is different compared with the property of the action in the land because the influence of resistance from the wave. Therefore, We think that we should change the action between land and water. As a basic research, land or water is detected with the sensor. As a result, autonomous behavior switching is acquired to humanoid robot that put on wet suit., The Japan Society of Mechanical Engineers, Japanese

  • Performance Evaluation of Recommendation Algorithms Based on Rating-recommendation Interaction
    山下 晃弘, 川村 秀憲, 飯塚 博幸, 大内 東, 情報処理学会論文誌数理モデル化と応用(TOM), 2, 2, 47, 57, 27 Mar. 2009
    The problem of information overload spreading across the Internet has been causing serious inefficiency in browsing and searching for information. As a way to overcome the problem, the recommender systems are recently used in many E-commerce sites. Many algorithms have been proposed to improve the accuracy of recommendation based on user ratings. The relation between recommender systems and users is rather interactive in the sense that recommendations decides which items are recommended to users and the results of ratings by users will affect the next recommendations. However, conventional studies have not considered the interactive aspects so much. Therefore, our aim of this paper is to propose a new evaluation model using multiagent modeling where the recommender system and agents (as users) interacts with each other. The properties of typical recommendation algorithms such as user-based and itembased collaborative filtering will be analyzed with our proposed model. Our results also suggest the possibilities to propose a novel and effective recommendation algorithm., 情報処理学会, Japanese

    In many E-commerce sites, recommender systems, which provide personalized recommendation from among a large number of items, are recently introduced. Collaborative filtering (CF) is one of the most successful algorithms which provide recommendations using ratings of items by the users. There are two approaches such as user-based CF and item-based CF. Additionally an algorithm which improves recommendation accuracy by unifying both of user-based CF and item-based CF was proposed. In the algorithm, a weight for unifying is a constant which obtained empirically. However, because the optimal weight for unifying is actually different by the situation, the algorithm should estimate an appropriate weight dynamically, and use it. In this research, we propose an approach for estimation of the appropriate weight based on collected ratings. Moreover, we discussed the effectiveness by using Movie Lens data., Information Processing Society of Japan (IPSJ), Japanese

    We report on learning landing control for the self-energy recharging of indoor blimp robots. Indoor blimp robots have potential applications in monitoring, surveillance, and entertainment. It might be necessary for blimp robots to fly for a long time to achieve these tasks. Since blimp robots cannot have a heavy battery, it is difficult to fly for long time. Therefore, we solved this problem by developing self-energy recharging control, i.e., docking to an energy charging station. We call it landing control. We introduce a way to learn landing control to tackle an unstable flying condition. The results of experiments show the effectiveness of the landing control. © 2008 International Symposium on Artificial Life and Robotics (ISAROB)., English

    MATSUMURA YUSUKE, KAWAMURA HIDENORI, OHUCHI AZUMA, IPSJ journal, 48, 6, 2097, 2105, 15 Jun. 2007
    The high-quality service provided by the large-scale tele-communication network constructed in the Internet such as the Gnutella is thought to be achieved by a certain feature network structure. Moreover, a feature structure is assumed to be generated with a certain simple generation rule in another research. This shows that there is a possibility that an effective design approach of the large scale network can be established if the design of the generation rule that generates the optimal structure becomes possible. Authors tried to archive a structural generation rule to make the communication efficiency on the telecommunication network considering these in this paper. Concretely, the network was modeled with the queueing network and a structural generation rule to minimize waiting time was investigated. As the result, it made clear that the generation rule can generate structures with small enough waiting time under som conditions., Information Processing Society of Japan (IPSJ), Japanese

  • Effect of the number of users and bias of users' preference on recommender systems

    Recommender System provides certain products adapted to a target user, from a large number of products. One of the most successful recommendation algorithms is Collaborative Filtering, and it is used in many websites. However, the recommendation result is influenced by community characteristics such as the number of users and bias of users' preference, because the system uses ratings of products by the users at the recommendation.
    In this paper, we evaluate an effect of community characteristics on recommender system, using multi-agent based simulation. The results show that a certain number of ratings are necessary to effective recommendation based on collaborative filtering. Moreover, the results also indicate that the number of necessary ratings for recommendation depends on the number of users and bias of the users' preference., SPRINGER-VERLAG BERLIN, English

    We focus on a method to calculate the estimated value for a probabilistic model in which each event is defined as a combination of several other independent events. The partially exhaustive investigation Monte Carlo method has been proposed by the authors for such model, and it can show higher performance than simple weighted sampling Monte Carlo method on the condition that the used sample number for estimating is limited. This method divides the event into two parts by a threshold parameter; one is composed by high-probability events, and another is by remaining events. To make this method for practical use, these are unclear appropriate threshold setting and a condition that this method works effectively. In this paper, we investigate the condition that this method works effectively, and propose the partially exhaustive investigation Monte Carlo method with automatic threshold parameter setting., Information Processing Society of Japan (IPSJ), Japanese

    Blimp robots are attractive as indoor flying robots because they can float in the air, land safely with low energy, and stay in motion for a long time compared with other flying robots. However, controlling of blimp robots is difficult, because they have nonlinear characteristics, are influenced by air streams, and is easy to be influenced of inertia. Therefore a robust and adaptive control system is needed for blimp robots. The applied research that paid its attention to the feature of indoor flying robot in recent years has prospered.
    Operating an indoor blimp robot for a long time is difficult for the payload is small, many batteries cannot be stacked. and the design of a thruster that has freedom and the entire blimp robot. Therefore, an autonomous charge that enables operation for a long time is needed.
    We developed a round orbit control to the Surveillance point for an autonomous of a blimp robot. The possibility of round surveillance three dimensional orbit controls was shown., IEEE, English

Indoor balloon robot might be applied to entertainment flight in an event hall, such as synchronized flight of multiple balloon robots, interactive balloon robot. It might be necessary for long term flight to achieve entertainment flight. However, indoor balloon robot cannot load heavy battery for long term flight. To achieve long term flight, one approach is autonomous recharging. In the case of low battery remainder, indoor balloon robot moves to charging station for recharging. For autonomous recharging, we designed charging station and docking control for indoor balloon robot., Information Processing Society of Japan (IPSJ), Japanese

  • Proposal of Partially Exhaustive Investigation Monte Carlo Method and Application to Decision-making of the TAC Agent
    KAWAMURA HIDENORI, ONODERA MASAKI, OHUCHI AZUMA, IPSJ journal, 46, 12, 3218, 3227, 15 Dec. 2005
    To design an autonomous-trading software agent for some kinds of game and electric commerce, the agent often has to cope with the situation that result of decision-making includes stochastic phenomena. In such case, it is necessary for the agent to consider expected evaluation value for possible results according to the probability of results, and Monte Carlo Method is generally used to calculate the expected evaluation value for such situation. In this paper, we suppose the situation that it is easy to enumerate high-probability results at low computation cost, and propose an improved version of Monte Carlo Method, i.e., Partially EXhaustive Investigation (PEXI) Monte Carlo Method. Moreover, we show the effectiveness of the proposed method by some computer experiments including the designing of TAC CLASSIC trading agent., Information Processing Society of Japan (IPSJ), Japanese

    A website is considered to be belonging to a certain category such as accommodations, restaurants, facilities and so on, as shown in the directory-typed search engines. Generally, a website includes valuable information such as links to or from other sites, many files with extensions and many text data, in terms of the category classification. In this paper, we investigate whether many websites belonging to a certain category have some common features or not. In particular, we show that some keywords are very important to classify websites to the categories. By using these analyzed keyword information, we present that many websites could be classified to an appropriate category with high precision when three categories (museum, restaurant and accommodations) related to tourism are treated as examples., The Institute of Electronics, Information and Communication Engineers, Japanese

    M Nagao, H Kawamura, M Yamamoto, A Ohuchi, Soft Computing as Transdisciplinary Science and Technology, 285, 294, 2005
    Recently, tourism activity analysis has been required in order to construct effective tourism policy and strategy for personal tour which became the mainstream Of Japan. In conventional tourism activity analysis, the information for analysis, i.e., tourism activity information, is collected on each tourist by using questionnaire, and then the analysis is carried out on the basis of it. However, it is difficult to realize effective tourism activity analysis in conventional method because the difficulty in collecting accurate questionnaire-based information collection has and detailed tourism activity information. In this paper, we propose a GPS log mining method in order to implement effective tourism activity analysis. GPS can automatically and continuously collect the position information where the GPS receiver exists. It is likely that an effective tourism activity analysis can be realized by extracting accurate tourism activity information from the information which is collected by GPS. We confirm the effectiveness of the proposed method through the experiments using the GPS log data collected from actual tourists in Hokkaido., SPRINGER-VERLAG BERLIN, English

    Toshihiko Takaya, Hidenori Kawamura, Yoshihiro Minagawa, Masahito Yamamoto, Azuma Ohuchi, Artificial Life and Robotics, 10, 2, 177, 184, 2005
    Blimp robots are attractive as indoor flying robots because they can float in the air, land safely with low energy, and stay in motion for a long time compared with other flying robots. However, controlling blimp robots is difficult because they have nonlinear characteristics, are influenced by air streams, and can easily be influenced by inertia. Therefore, a robust and adaptive control system is needed for blimp robots. The applied research that has studied the features of indoor flying robots in recent years has prospered. Operating an indoor blimp robot for a long time is difficult because the payload is small, multiple batteries cannot be stacked, and the design of a thruster that gives freedom to the entire blimp robot is difficult. Therefore, an autonomous charge that allows operation for a long time is needed. We have developed a method of landing with orbital control of the charge point that gives autonomy to a blimp robot. The possibility of landing with orbital control is shown. © ISAROB 2006., English
  • Entropy and mutual information analysis of collective behavior in slime Mold model
    K Nishikawa, H Kawamura, A Ohuchi, Soft Computing as Transdisciplinary Science and Technology, 316, 323, 2005
    In the research of a multiagent system, the indicators such as a task achievement ratio and a payoff have been used for analyzing a system. These indicators are important for the point that agents need to accomplish a task. However they are inadequate to make clear the entity of phenomena that occur in complex system, because they are specialized in the target system and the analysis is also specialized. In these respects the approaches that analyze a system quantitatively are begun to investigate in recent years. In our research, we propose the approach that analyzes a multiagent system quantitatively by focusing on the dynamics of a system and interaction among multiagents. We use two indicators, i.e., entropy and mutual information, for analyzing a system. Entropy estimates the behavior of an agent and mutual information estimates interactions between two agents. For verifying these propositions, we conduct verification experiment in the simple slime mold model. The result shows a relationship between agents ' behavioral patterns and two indicators, therefore our approach using entropy and mutual information is available for analyzing a multiagent system., SPRINGER-VERLAG BERLIN, English

    Balloon robots have attracted attention as new type indoor robots for various applications, e.g., observation, guidance, and amusement flying. A balloon robot can float and move long time in 3-dimensional space by low energy. However, it is difficult to control positioning of a balloon robot because it has great inertia and is easily effected by a little air stream of a conditioner. Positioning control under usual indoor environment is key technology to realize an autonomous balloon robot. In this paper, we develop the indoor-type balloon robot system with a light wireless vision camera. The balloon robot is controlled to keep at the target position based on simple vision processing and PD-controller. Vision processing is realized by perceiving a red circle on the floor as a landmark. In the experiments, several PD settings are investigated for positioning control, and we conclude the paper by that P-controller is suitable to keep at the target position and PD-controller successfully works to go in the direction of target from far position., Information Processing Society of Japan (IPSJ), Japanese

    In this paper, we propose a GPS log data mining method for acquisition of tourism information. Recently, the number of tourists which utilize rent-a-car has extremely increased according to shift of tourism type from group tour to personal tour. Therefore, in this research, we perform the extraction of personal behavior information which is effective for tourism information from GPS log data in rent-a-car tour. Currently, the position detection with high accuracy can be performed by using GPS because SA which leads to decrease of accuracy has been removed.

    In most presented researches on multi agent systems, the macroscopic system performance is discussed with such specific measures as gain or achievement. These measures are still important, but when we observe the complex system, it is impossible to understand the essentials of its behavior only using these measures. Therefore we propose an analysis method with entropy and mutual information, the essential terms to analyze the complex system related to macroscopic characteristics. Consequently, we verify the validity of quantitative analysis using entropy and mutual information., Information Processing Society of Japan (IPSJ), Japanese

While this robot can pass over terrain that may be impossible for land-based robots to negotiate, it is hard to control autonomously because it is subjected to strong inertial forces and air resistance. We are now designing an autonomously controlled indoor blimp, which will be suitable for use in for inspections or monitoring tasks and as an amusement robot or guide robot. © 2003 by Springer Science+Business Media New York., Springer New York LLC, English

    In generally, we often play a game against the entity, which we do not know what really is. In the case, the result of the game is often dependent on the scale of participant and the other players' strategies, but we may not get their information. And all we can know is the result. We are to investigate the player's behavior and the behavior as a whole of players in such the environment. So, we make a simple model to study the behavior of players when against the entity whose decision-making system is not clearly known to them., Information Processing Society of Japan (IPSJ), Japanese

  • X-Economy: A common simulation platform for artificial market and artificial economy
    H Kawamura, K Kurumatani, A Ohuchi, PROCEEDINGS OF THE 6TH JOINT CONFERENCE ON INFORMATION SCIENCES, 1069, 1072, 2002
    We propose a common simulation platform in artificial market and economy called "X-Economy," which provides common agent libraries and a server for multi-agent modeling and simulations in financial and economic systems. Multi-agent approach to economic systems have been successfully developing, and many simulation-based researches have been carried out. Since they basically lack compatibility about agent architecture and communication protocol design, it is difficult to examine and compare the works which are, achieved by others. In X-Economy, we provide a common communication protocol and agent architecture and we aim to increase easiness of exchanging agents used for modeling, simulation, and analysis of financial and economic systems. Especially, we introduce some research programs in X-Economy., ASSOC INTELLIGENT MACHINERY, English

    The economic and finance systems related to dynamic real world are too huge complex systems to understand the principles of these behavior. Many researchers, i.e., economists, mathematicians, sociologists, computer scientists, and so on, have hoped for long time to model and clarify the inner meaning of such phenomenon. The one of difficulty for these researches is for lack of paradigm that describes the relationship between realistic economic agents with bounded learning or evolving rationality and the emergence macro behavior as aggregation of such agents.

    In the field of economics, it is said that a market price shows random-walk behavior and cannot be expected. The theory of "Efficient Market Hypothesis" is the basis of this behavior. This theory is considered that all traders are homogeneous. However, it is appropriate to a trader is heterogeneous. And price fluctuation like a bubble phenomenon in recent years is the phenomenon which cannot explain sufficiently in the economics. Then, the artificial market research by the agent base simulation is appearing as new approach for solving such a phenomenon.

    In this paper We introduce mutual choice mechanism into the norms game instead of direct penal regulation and reformulate the norms game with mutual choice. In order to examine how the proportion of metanorm players to all players influences on the establishment of norm in the metanorms game with mutual choice, we perform simulation under several proportions of metanorm players. We exclude the game theoretic assumption of uniformity as the metanorm player and observe thf frequency of the establishment of the norm. As a result, we confirm the robustness of mutual choice against insufficiency of the metanorm players., IEEE COMPUTER SOC, English

    In this paper, we focus on evolutionary emergence of communication among multi-agents. As the stage of investigation, we prepare the ants war which needs artificial ant agents to interact each other to win the opponent. Ant agents are constructed with 2-layers neural networks, and evolved by genetic algorithm. Throughout several trials of evolutionary processes, we observed the emergence of two types of pheromones, i.e., the attractive pheromone and the repulsive pheromone. The evolved pheromones were very effective when used in larger number of agents, and this fact represents the emergence of collective intelligence and pheromone communication. According to these results, the collective intelligence and communication among agents are discussed., I O S PRESS, English

    The number of foreign tourists visiting Japan has been increasing. It is essential to analyze the needs of foreign tourists in order to promote inbound tourism in Japan. This research was carried out by analyzing word-of-mouth about Japan travel from Japanese tourists and foreign tourists to investigate the differences in destination image of a particular tourist attraction using a text mining approach. Moreover, the information in the official sightseeing websites was analyzed with respect to Japanese and English text data in order to compare the results of Japanese and foreign tourists’ destination images of the tourist attraction. The framework that extracts distinctive tourism information from three perspectives: Japanese tourists, foreign tourists, and tourism promoters was proposed for the purpose of developing regional tourism support tool.

    The analytic hierarchy process (AHP) is a method for decision-making that considers uncertain situations or multiple evaluation criteria. In the AHP, a decision maker compares two elements between evaluation criteria and alternatives. Therefore, comparing all pairs is difficult when evaluating many alternatives. In this study, we present the comparison support method for evaluating many alternatives when a decision maker needs to decide the highest priority alternative. The comparison support method stops pairwise comparisons when the best solution, i.e., the highest priority alternative, is found, even if all pairs have not been compared. We represented a modeling of determine the best alternative using the AHP include comparison support system.

    In this research, we focused on the service infrastructure on a society, which is a set of facilities utilized by many citizens, and developed a simulation model with many citizen agents and service facilities for studying the way to reduce social congestion. In computer simulation model, the visiting plans of agents are shared via the central server and each agent plan is individually optimized by the information based on the server. Through the experiments, we showed that the social congestion is reduced by such information sharing.

    1.自由エネルギーに基づいたハイブリダイゼーション過程の解析
    本研究では,ある一本鎖DNAとその完全相補配列,及び,競合する塩基配列を混合した溶液中で起こるハイブリダイゼーションの特徴を自由エネルギーや融解温度の立場から明らかにした.
    ある塩基配列Aと完全相補な塩基配列B,及び,Aと部分的に相補な配列を含む塩基配列Cが競合する反応系において,AとBの結合体の最小自由エネルギー,および,融解温度,また,AとCの結合体の最小自由エネルギー,および,融解温度との関係からAとCが結合してしまうミスハイブリダイゼーションの発生割合の分析を行った.検出にはDNAに修飾した蛍光のクエンチングを利用した.結果的に,最小自由エネルギー,および,融解温度の差がミスハイブリダイゼーションに与える影響について,実験結果からモデル式を導出することに成功した.
    2.DNAタイルのための塩基配列設計支援システムの構築
    昨年度の研究成果を受けて,DNAタイル設計のための塩基配列設計支援システムの構築を行った.DNAタイルは,ナノ構造の形成やタイル計算に用いることが可能であることから近年注目を浴びている.しかしながら,DNAタイルは何本もの一本鎖DNAの結合体であることからその構造安定性を求めることは困難であり,これまで,ヒューリスティックな方法として,重複する連続した部分塩基配列を避ける方法が使用されてきていた.
    本研究では,DNAタイルの構造安定性を見積もる方法として,自由エネルギーを用いることにした.2本の一本鎖DNAからできる主な結合体の自由エネルギーを見積もる方法は,これまでの研究で洗練されたものとなっている.このため,DNAタイルの構造体を2本の一本鎖DNAからなる部分に分けて,DNAタイルが望み通りに生成されたときの結合体の自由エネルギーが最も安定となるような尺度を設計することを目的としている.本研究では,設計支援のためのツールを開発した.DNAタイル設計の際には,各部分配列同士の非特異的結合を避けたり,融解温度やGC含量などを考慮したり必要があり,それらを見積もるツールが必要である.また,作成した配列の解析や,山登り法による最適化手法による配列の自動生成も可能である.

  • テーマパーク問題におけるインテリジェントマスサポート理論に関する研究

    2003 - 2005
    川村 秀憲
    本研究では「テーマパーク問題」を提案し,インテリジェントマスサポート理論に関する理論構築を目的とする.テーマパーク問題とは,複数のアトラクションに対する選好を持ったエージェントがテーマパーク内を巡回する際,個人の効用を下げずに全体の混雑度を減少させる巡回プランを提示するための動的・複合的スケジューリング問題である.
    平成17年度は,エージェントが混雑情報に基づいて近視眼的に混雑回避行動をとると仮定したとき,どのような混雑情報を提示することが全体の混雑緩和に寄与するかに焦点をあてて研究を行った.
    具体的には,ユーザが次に訪問するアトラクションを混雑情報システムに入力させ,各アトラクションの混雑状況に未来の混雑の予測という情報を付加することで各エージェントが自律分散的に混雑回避した際の効果が全体の混雑緩和に寄与するということが確かめられた。
    また,エージェントから情報収集を行いながら適切に混雑情報を提示するだけではなく,事前に全てのエージェントの制約条件が明らかになった状態で遺伝的アルゴリズムを用いて静的に訪問順序を最適化したものとの比較を行った.
    その結果から テーマパークのように限られた資源をたくさんのユーザで利用しなければならない場合,単純に均一的に負荷を分散させるよりも,わざと1,2のアトラクションにエージェントを集中させ,残ったほかのアトラクションでの資源利用効率を上げることが全体の混雑緩和に大きく寄与することがわかった.これは,特定のアトラクションの利用効率を悪化させても,残りのアトラクションの利用効率を上げることでシステム全体内のエージェントの数を減少させることができるので,結果的に全体の利用効率化を図ることができると言うことである.
    この結果は,例えばユビキタス通信を装備したインテリジェントカーナビなどを開発する際に応用可能な成果が得られたと思われる.

    In this research project, we proposed the new information security system at the molecular level for personal genome data. Important data such as Personal genome data can be stored as a DNA sequences, and can be readout when it is needed. In the proposed system, however, it is impossible or so hard to readout without the keys, because some kind of dummy DNA data are included in the pool with the stored data. We proposed two kind of security system.
    (1)Data lock by DNA modification
    Data is stored into DNA with some modifications, which can be removed only by the key primer. We demonstrated that the target data can be readout only if we can use the key primer by some chemical experiments.
    (2)Data lock by the hierarchical DNA memory based the nested PCR
    Data is stored with some DNA blocks, which are regarded as addresses of memory. In order to readout the data from the pool of these DNA memories including some dummy DNA, nested PCR with some key DNA are used. We verified that the target data can be extracted and readout from 27 kinds of DNA memories by some chemical experiments. Furthermore, we demonstrated that the target data can be extracted from 65,536 kinds of the pool of DNA memories.
