  Japanese, Scientific journal, In vehicle routing problems, it is required to compute the necessary customer-to-customer routes within a settime frame, and to perform route searches that take into account the preferences of individual drivers at the time ofroute search. In this paper, we propose a road network hierarchization method aimed at reducing the total computationtime for route search and performing route searches that consider the preferences of drivers. The proposed methodconstructs a hierarchical network based on betweenness centrality, one of the centrality measures in network analysis.To verify the effectiveness of the proposed method, computer experiments were conducted on the road network of a14 km square area in the central part of Sapporo city, with multiple drivers’ preferences for narrow roads prepared.The total computation time for route search, the cost of routes, and the average route length were evaluated. As aresult, by using the proposed method, the total computation time for route search was reduced to 4 ∼ 7% of the exactsolution, and the cost of routes worsened by about 5 ∼ 10%. Additionally, regarding the average route length, whereasthe Euclidean distance, frequently used as a measure for the length of routes between a delivery base and customers invehicle problems, tends to result in an error of about 30 ∼ 40% when compared to the exact solution, the applicationof the proposed method has been able to contain this error to less than 10%, thereby confirming the effectiveness ofthe proposed method.

  Japanese, Scientific journal, Kerosene delivery is a service that regularly supplies kerosene to household tanks to prevent them from runningdry. Delivery companies create kerosene delivery plans to maintain tank levels and implement deliveries based onthese plans. We formulate the Kerosene Delivery Planning Problem (KRP) and propose a solution method that utilizesa problem partitioning approach through the rolling horizon approach, combined with a hybrid method named HAIRthat integrates tabu search and integer programming. From experiments on parameter search, it was confirmed that thevalue ofMaxIter for HAIR should be set as a priority. Furthermore, in experiments targeting a single season, it wasobserved that the evaluation value of the proposed method improves by about 10% compared to the evaluation valuecalculated from actual delivery records. It was also confirmed that the parameters of the rolling horizon approach,specifically W and S, should be prioritized.

  Japanese, Scientific journal, In Japan, declining birthrates have necessitated compact cities and reorganization of public transportation,particularly bus routes. Effective transportation planning requires Origin-Destination (OD) data, which is challengingto collect due to high costs. This study develops a system to estimate bus passenger OD from videos captured onroute buses, integrating object detection, tracking, metric learning, and assignment algorithms. Videos of passengersboarding and alighting were recorded, and human bounding boxes were annotated. Model selection and training wereconducted to assess accuracy and identify improvement strategies. The research contributes to cost-effective OD datacollection, offering scalable solutions for public transportation systems. It demonstrates how advanced tracking andmatching algorithms can be applied in urban mobility analytics, potentially optimizing public transport networks.This study enhances public transport efficiency, providing a framework for applying advanced technologies in realworldscenarios and extending methodologies for accurate, cost-effective data collection across various fields.

  Japanese, Symposium, 北海道を始めとする積雪地帯において，道路除雪業務は道路交通を維持する重要な役割を果たしている一方で，除雪作業を行う従業員の業務負担は大きい．除雪業務の出動判断は局所的な天候の変動によって出動判断が覆ることが多いため，除雪作業員は休日でも出動に備えておく必要があり，除雪従業員の大きな負担となっている．
  このような背景に基づき，本研究では担当者の行う除雪出動の判断が覆らず，除雪対象範囲を安全に遠隔監視するために，除雪出動の決定に必要な情報を自動で収集し，可視化する除雪出動の意思決定支援システムの開発に取り組んでいる．本稿では，除雪出動決定支援システムの一部として既に実用化されている収集した道路の積雪状況や気象情報を可視化するための除雪関連情報共有サイトを構成について述べる．また，除雪関連情報共有サイトに追加して掲載する情報として，定点カメラ画像における積雪割合推定機能を開発している．深層学習を用いて定点カメラ画像の積雪範囲を数値化する積雪割合推定モジュールを提案し，実際の定点カメラ画像に対する推定結果を確認する．

In this paper, we developed a system to automatically generate articles for Keirin. Our system predicts race results including race development using Transformer, and generates articles by a rule-based method. Experiments on dataset show that our predictor performs better than the odds and that it is possible to make a profit by selecting tickets based on the predictor's output. The system-generated articles achieved the same or better score as the existing articles in human evaluation.

  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.

  Japanese, Scientific journal, 長年減少していた競輪の車券売上はインターネット投票の売上増加の影響によって，近年では回復傾向にある．そこで，競輪事業を活性化するためにはWeb上での積極的な情報発信が必要である．競輪の情報発信の例として予想記事があげられる．予想記事は専門家によるレース結果の予想が記述された記事であり，情報発信として有効である．現在，競輪の予想記事は全国で毎日実施されている約60レースの各レースについて人手で執筆されている．また，前日のレース結果に応じて参加選手が決定されるということもあり，予想記事の執筆の負担は大きい．そのため，予想記事を含むコンテンツの自動生成技術への高いニーズがある．本研究の目的は，レース開始前の情報から予想記事を自動生成することである．記事の自動生成のために，機械学習によりレース結果を予測し，予測結果を説明する記事をテンプレートによって生成した．
  Keirin ticket sales which had been decreasing for many years have been recovering in recent years because of increase sales on the Internet. So, proactive information provision is necessary to activate the Japanese Keirin business. There is an article describing prediction of the race result as example of information provision. However, the burden of writing articles by hand is great. This is because the number of races per day is about 60 races and it is very large. Another reason is that participating cyclists will be decided according to the race result of the previous day. Therefore, there is a strong demand for a technique for automatically generating content including articles. The purpose of this research is to automatically generate articles from the information obtained before the start of the race in Japanese Keirin. In order to automatically generate articles, we predict race results by machine learning. And, we generate an article explaining the predicted results using the template.

  Japanese, Scientific journal, 非正規労働者を主力とする事業所では欠勤が発生しやすく代替従業員確保業務の負担が大きいため，シフト表修正の効率化が求められている．代替従業員確保の際には電話による依頼が行われ時間的，精神的負担が大きい．本研究では近年導入が進むメッセージングアプリの利用を想定した依頼回数，過剰人数に主眼をおく効率的な代替出勤依頼手法の開発を行う．検証環境として実データをもとにシミュレーション環境を作成し，手法導入による効果を検証する．検証実験により提案依頼手法は過剰確保を抑えながら依頼回数を低減するのに有効であることを示す．
  An efficient shift schedule correction method is required in offices where there are a lot of part-time workers because their high absenteeism rate makes substitute worker securing heavy. A request is made by telephone when securing a substitute worker, which is burdensome temporally or mentally. This study develops efficient request method using messaging app focusing on the number of request and excess staffing. A simulation environment is created based on real-world data and used for examining the effects of adopting our method. Experiment results show that our request method is effective for reducing the number of request while curbing the rise in the number of excess staffing.

But people concern about security on the cloud service and still feel resident to storing enterprise data in external server. So people interest in private cloud environment. In this paper, we evaluate private cloud system including Eucalyptus, an open-source software implementation of cloud computing system like Amazon EC2. Evaluations are about basic performance, management and recovery, web application performance for this system. Finally, we conclude if limited to small-scale, enterprise private infrastructure for short time use, it can be a good private cloud system

  Japanese, Scientific journal, 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 ...

  Japanese, Scientific journal, 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.

  Japanese, Scientific journal, 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...

  Japanese, Scientific journal, 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...

  Japanese, Scientific journal, In order to evaluate the cost and effect quantitatively in the feasibility study of deploying video-conferencing systems in prefectural medical associations, we developed and applied a cost-effect model to Hokkaido Medical Association (HMA). We introduced a typical model specification for the videoconferencing systems and evaluated the effect by the reduction of the distance and time of transportation, assuming some fixed replacement ratios, which indicate what ratio of the existing meetings is to be replaced by the videoconferences. As for the cost, we evaluated the accumulated cost savings for several consecutive years in terms of the following five parameters: the travel expenses, the travel expense reduction factor, the initial system construction cost, the communications charge, and the replacement ratio. As the result, we obtained the estimate that the accumulated cost savings would exceed the system construction and operation cost in two (three) years if the replacement ratio is 100% (50%). We conclude that the deployment of videoconferencing systems to HMA is desirable from the cost-effect perspectives.

  Japanese, Scientific journal, 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.

  Japanese, Scientific journal, In this paper, we focus on the emergence phenomenon related with artificial pheromone communication and swarm intelligence among many agents in Ants War environment, in which two colonies of artificial ant agents compete for the limited number of food items in order to survive in evolutionary process. The purpose of this research is to clarify the emerging process of communication and the relationship between communication and swarm intelligence. For investigation of communication, we introduce Shannon's entropy and the amount of information to externally measure “the effectivity of communication signals for decision-making of agents” and “the specialty of environmental situation in sending communication signals”. In computer simulations, we confirm that the amounts of information of pheromone sensory inputs and selecting of sending pheromone signal are increased with correlation according to the progress of evolution. These experimental results derive that evolutionary communication is incrementally formed by the interaction among agents with self-organization and the self-reinforcement in communication-loop of repeated sending and receiving signals. In addition, we confirm the level of swarm intelligence with evolved pheromone communications by measurement of the correlation between the size of swarm and the performance in Ants War. In investigation, we find that the size of swarm and emergence of swarm intelligence are strongly related. The results introduced in this research will be a base for investigation of multi-agent communications.

• Evaluation of Deep Neural Network Using Stereo Camera in Adaptive Cruise Control

  In recent years, research on end-to-end autonomous driving systems has become active; however, high-precision inference requires high-performance machines for both training and deployment, which imposes significant burdens on research and commercialization. If stereo cameras are employed, then not only can depth estimation be omitted through algorithmic distance measurement, but also, by acquiring both image and distance information with a single sensor—potentially eliminating the need for sensor fusion—the model is expected to be simplified. In this study, as an initial investigation into an end-to-end autonomous driving model using stereo cameras, we develop a model for adaptive cruise control, a fundamental autonomous driving task. We modified the Transfuser model to predict vehicle acceleration from stereo camera data. Evaluation on roughly 160,000 frames from Japanese public roads showed high accuracy in monotonous environments with minimal acceleration or deceleration, suggesting the practical viability of this approach. Conversely, in conditions of significant acceleration/deceleration, uphill driving, or abrupt lighting changes, accuracy decreased; we analyzed the causes and proposed improvements., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference
• Proposal of a Classification Method of Near-Miss Incidents from Disaster Response Verification Reports Using Deep Language Models

  In recent years, municipalities have increasingly utilized disaster response verification reports to enhance their disaster preparedness. These reports document near-miss incidents encountered by administrative personnel, and the collection and classification of such cases are essential for improving disaster management measures. Currently, case extraction is performed manually, followed by classification into 12 categories based on the context. However, even when limited to flood-related verification reports since 2017, there are 85 reports spanning a total of 7,053 pages, making manual extraction and classification increasingly unfeasible. Thus, a tool to support the extraction and classification of near-miss cases is in high demand. Our previous research proposed a BERT-based method for extracting near-miss incident sentences with high accuracy. This study extends that approach by classifying extracted sentences into 12 categories using BERT. The model is trained with manually labeled data. Evaluation using Top-3 accuracy shows that while performance for low-data categories remains a challenge, accuracy for high-data categories reaches a practically usable level., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  When creating manuals, it is important to design a table of contents (TOC) that makes it easy for users to find the necessary information. However, constructing a TOC based on the users' perspective is not straightforward, requiring specialized knowledge. To solve this problem, this study proposes an automatic TOC generation method using large language models. Specifically, we design prompts that incorporate the rules and expertise used by manual creation professionals, thereby generating a TOC structure in which users can easily find information. We compared the table of contents structure generated by the proposed method with the existing table of contents structure, and confirmed that it is equivalent to the structure created by experts. Furthermore, through the experiments conducted in this paper, we discuss the method’s potential to automatically generate a generic TOC structure, as well as possible directions for further enhancement., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference
• Snow Removal Dispatch Prediction Using Road Surface Image and Weather Information with L1 Regularization

  Snow removal from roads in snowy areas during the winter is essential for maintaining road traffic and infrastructure. However, since the decision to dispatch snow removal operations is greatly influenced by changes in weather and road conditions, the decision made by the person in charge is often reversed, which not only forces the snow removal crew to prepare for uncertain dispatch, but also places a psychological burden on the person in charge. To solve this problem, we propose a snow removal dispatch prediction method that integrates road surface images with diverse weather information, utilizing L1 regularization for feature selection. Specifically, we automatically select effective features for model learning from a large set of candidates including both qualitative and quantitative data such as hourly temperature, snowfall, and wind direction thereby enabling high precision predictions. Our experimental results show that the proposed method achieves higher accuracy compared with both manual judgment by experienced personnel and a conventional logistic regression model., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  A selection mechanism for Japanese haiku, world's smallest fixed form of poetry, is developed to select haiku of interest to the user from a set of haiku generated by a deep autoregressive model. This is achieved by training a deep model that estimates the probability of occurrence or similarity of the haiku to be selected by learning the user's previous haiku works. 100 million haiku are generated and selected using a large-scale language model that has additionally learned 400,000 haiku data. We additionally train a deep language model using several thousand haiku created by users in the past as training data, and decide which haiku to select from the acquired model. With the cooperation of haiku poets, we evaluated the effectiveness of the autoregressive model and the masked language model by presenting the selection results with different numbers of parameters. The experimental results revealed the high performance of the autoregressive model and the importance of using the ratio of the estimated results of the model trained only on the case data and the model trained on haiku in general, rather than simply selecting the haiku with the highest estimated probability of occurrence., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  Detailed information for comparisons between products is necessary in consumers’ product purchasing process, especially during the information search and choice evaluation phases. However, conventional product descriptions, which are the main source of information, tend to focus only on the product in question, and thus do not adequately express the differences between products. To solve this problem, garments are treated as target products, and a caption-generation method that emphasizes the differences between pairs of garment images using a deep-learning model for image caption-generation is proposed and its effectiveness verified. The proposed method selects and outputs captions that express differences in features from a set of captions generated for input-garment image pairs. Subject experiments confirmed that the proposed method accurately represented the feature differences between garments and provided useful information for consumers to compare garments. In particular, the proposed method is highly effective for garment pairs with similar features., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

• Generation of Captions Based on Attribute Predictions Highlighting Differences between Garment Image Pairs
  阿部晃平; 横山想一郎; 山下倫央; 川村秀憲, 人工知能学会全国大会論文集(Web), 38th, 2A6GS1005, 2A6GS1005, 2024, [Domestic magazines]
  Detailed information for comparisons between products is necessary in consumers’ product purchasing process, especially during the information search and choice evaluation phases. However, conventional product descriptions, which are the main source of information, tend to focus only on the product in question, and thus do not adequately express the differences between products. To solve this problem, garments are treated as target products, and a caption-generation method that emphasizes the differences between pairs of garment images using a deep-learning model for image caption-generation is proposed and its effectiveness verified. The proposed method selects and outputs captions that express differences in features from a set of captions generated for input-garment image pairs. Subject experiments confirmed that the proposed method accurately represented the feature differences between garments and provided useful information for consumers to compare garments. In particular, the proposed method is highly effective for garment pairs with similar features., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  Shumpei, Otokita; Soichiro, Yokoyama; Tomohisa, Yamashita; Hidenori, Kawamura, 社会システムと情報技術研究ウィーク, 2023, Mar. 2023
  中古ブランド品のB2Bオークションでは，多数のアイテムのオークションが並列して実施されるため，参加者はすべてのアイテムの価値を検討することが困難であり，入札するアイテムの選択や，留保価格の適切な設定が課題である．本稿では，こうした課題を入札アイテムの推薦や留保価格に対する不落札率の推定により解決するため，オークションにおける多関係推薦モデルMultiRecを用いたユーザ別入札行動予測をオークションデータに適用し，その精度から利用可能性を検証した．
  In B2B auctions of brand-name items, participants have difficulty in considering the value of all items because many items are auctioned in parallel, making the selection of items to bid on and the appropriate setting of reserve prices challenges. In this paper, to solve these problems by recommending items to bid on and estimating the percentage of unsuccessful bids relative to the reserve price, we applied the multi-relational recommendation model MultiRec to auction data to predict bidding behavior by user, and examined its accuracy and usability in auction data., 情報処理学会, Japanese

  本稿では，衣服の印象に基づくトップスとボトムスのコーディネートの推薦をおこなうシステムを開発した．本システムは，深層学習モデルを用いてユーザーの衣服画像の印象を推定して，推定結果をユーザに提示する．さらに，ユーザーの衣服と系統の近い衣服を推薦候補として，トップスとボトムスの相性と印象に基づいて，推薦するコーディネートを決定する．ユーザーに対するアンケート調査を実施して，本システムの有効性を確認する。
  In this paper, we develop a system that recommends coordinated tops and bottoms based on the user's impression of the clothes. The system uses a deep learning model to estimate the impression of a user's clothing image and presents the estimated results to the user. The system then selects clothes that are close in lineage to the user's clothes as candidate them for recommendation, and determines the coordination to recommend based on the impression and compatibility of the tops and bottoms. A questionnaire survey of users will be conducted to confirm the effectiveness of this system., 情報処理学会, Japanese

  ファッション業界では感性が重要な地位を占めており，「かわいい」「ガーリー」といった感性を基に商品の開発や販売に関わる判断が下される．しかし，服飾に対する印象は受け手により変わり得るため，定量的な分析が出来ない．このため，人の印象を定量的に評価するシステムのニーズがある．
  本研究では，アノテーションのコストを一定としたときに画像枚数と一枚にタグ付けする人数を変化させ，深層学習を用いた推定結果を比較することで，印象を推定するためのデータセットの構築方法を検討した．
  In the fashion industry, based on impression such as "girly" or "cute" , development and sale of goods are carried out. However, the impression vary depending on the recipient, there is a need for a system to quantitatively evaluate the impression of people.
  In this study, we change the number of images and the number of people who tag each image when the cost of annotation is constant, and compare the estimation results using deep learning.
  Based on these results, we examined how to construct a data set for estimating impressions., 情報処理学会, Japanese

  予期しない欠勤により空いたシフトを代替の従業員で補填するため，
  従業員に依頼を行う代替出勤依頼という業務がある．
  この業務では従業員に個別に連絡する必要があるため，管理者の負担が大きかった.
  近年，メッセージングアプリを用いて依頼業務を自動化しようという動きがある．
  本稿では，メッセージングアプリを用いた依頼業務における，
  一か月間の代替出勤依頼の引受回数の平準化・充足率の向上を目的とした
  依頼アルゴリズムを提案する．
  依頼アルゴリズムの検証には文献[1]を発展させたマルチエージェントシミュレーション環境を利用した．
  検証の結果，受諾確率について降順の依頼順の場合に最適依頼人数戦略が有効であることが確認された．
  In an alternative attendance request, managers ask employees to fill in a shift that has been vacated due to unexpected absence.
  It is necessary to contact the employees individually, which places a heavy burden on the the managers.
  Some companies try to use a messaging application to automate the task.
  In this paper, we propose a request algorithm for leveling the number of acceptance
  for one month and improving the sufficiency rate using a messaging application.
  We use multi-agent simulation based on our study[1] for testing the algorithm.
  The experiments show that optimal request number strategy is effective when requesting in descending order of acceptance rate., 情報処理学会, Japanese

  近年のECサイト市場の拡大に伴い,掲載される商品数は非常に多くなっている.そのためECサイト担当者の掲載商品の紹介文作成の負担が大きい.本稿では,担当者を想定利用者として,説明文作成の負担を軽減しつつ,より多くの商品に対して高品質な商品紹介文を提供するために商品紹介文作成支援システムの開発を行う.対象の商品として国内で豊富な種類が取り扱われている日本酒を取り上げる.本システムを利用して作成された商品紹介文や担当者の作成した商品紹介文を評価するために,日本酒 3 品の紹介文が掲載されたメールをメーリングリストの登録者 34 万人に配布した.メールに掲載されている商品掲載ページへ遷移するためのURLのクリック率に基づく評価を行い,作成支援された紹介文のクリック率が有意に高いことが示された.
  With the expansion of the EC site market in recent years, the number of products posted has become extremely large, which places a heavy burden on EC site managers in creating introductory sentences on the products posted. In order to provide high-quality product introductions for more products while reducing the burden of creating descriptions, we will develop a product introduction creation support system. In order to evaluate product introduction sentences created using this system and product introduction sentences created by the person in charge, register an e-mail with three sake introductions on the mailing list. The evaluation based on the click rate of the URL used to transit to the product listing page in the email showed that the click rate of the introduction sentence supported was significantly higher., 情報処理学会, Japanese, Technical report

  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., The Japanese Society for Artificial Intelligence, Japanese, Technical report

  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., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  The creation of art using deep learning has been paid attention to in recent years. Also, there is a haiku as an art that has long been popular in Japan. In this research, we demonstrate the usefulness of deep learning as art creation by making haiku from motifs, which is a general method of creating haikus, using deep learning. First, we train LSTM based on a large amount of past haiku, let it generate a stringa. Second, we extract the ones that satisfy the condition as a haiku from the generated character string and calculate the evaluation value as to whether it fits the motif image or not. If the evaluation value is high, it is assumed that the generated haiku matches the motif image. In this process, we conducted an experiment to confirm whether LSTM was able to learn rules as a haiku., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  In recent years, the development of autonomous operation technology has been actively carried out in a various research institutions and companies. Many experiments are conducted in public road to confirm whether one autonomous car can drive safely. However, autonomous operation with inter-vehicle communication has not been much researched. In this paper, we implement mutual concessions of autonomous cars with Deep Q-Network (DQN), which is a deep neural network structure used for estimation of Q-value of the Q-learning method. To verify the effectiveness of mutual concessions, we develop an experiment environment for verification of autonomous operation with radio control (RC) cars. We implement mutual concessions of autonomous cars at the confluence in the roundabout. DQN is applied for the decision-making mechanism to decide velocity in the roundabout based on the position of others and the status of congestion. As a result of our experiment, we confirmed that the autonomous cars with DQN can realize high transfer efficiency in the roundabout., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  Shift scheduling has been studied in various fields for many years, but little consideration has been given to absence which occurs after determining shift. Recent years, research on shift rerostering has been carried out, but most of them tries to correct shift with minimum cost. While alternative attendants selection requires an enormous amount of labor, this operation hasn't been taken into account. In this research, we make an agent-based simulation environment, then investigate alternative attendants selection methods on some easy cases., The Japanese Society for Artificial Intelligence, Japanese, Summary national conference

  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.

  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, Summary national conference

  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, Summary national conference

  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, Summary national conference

  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, Technical report

  In these days, the internet, chat and weblog have lowered our barriers to the posting comments and information on Web sites. Because they are easy to use, their users are increasing yearly. These comments and information involve user's opinions, impressions and evaluations of certain objects, so there is a need for extraction of valuable information from these comments posted by many people. But it is harder to analyze those free descriptions quantitatively than to analyze numerical data. In this paper, we propose an estimation approach by using Rakuten GORA reviews.

  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, Technical report

  Collaborative filtering is one of the most popular and effective recommendation algorithms based on user-user or item-item similarity. 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. Additionally, we propose and evaluate similarity computation method based on optimization., The Institute of Electronics, Information and Communication Engineers, Japanese, Technical report

  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, Technical report

  In this paper, we propose a method of learning docking control of autonomous recharging for indoor blimp robot. Indoor blimp robot can fly in a three dimensional space. For this feature, indoor blimp robot might be applied to entertainment flight in an event hall, and searching for human beings in destructive buildings, etc. To achieve these applications, it might be necessary to fly for long term and to trace orbit accurately. There are many researches for tracing orbit for blimp robots, but it is rare to research for long term flight for indoor blimp robot. Indoor blimp robot cannot load heavy battery for flying longer because of payload restriction. To achieve long term flight, one approach is autonomous recharging. We proposed autonomous recharging system in the past papers. But its control does not be enough to accomplish every time recharging. We designed a new control system for blimp robot. This control is based on learning control. We compare a new approach with a past approach. In the end, we conclude that a new approach is suitable for an autonomous recharging for indoor blimp robot., Japan Society for Fuzzy Theory and Intelligent Informatics, Japanese, Summary national conference

  As the number of individual tourists increases, Web browsing is becoming one of the methods to gather tourism information such as restaurants and accommodations. We can distinguish two types of tourism information. First, there is objective information such as address and telephone number. Then, we can talk about subjective information, such as evaluation given by an individual. While, browsing tourism information on major sightseeing sites, these sites usually have a lot of advertisements and there are only a few candid opinions of the users. Further, the individuals post various articles on the Weblog, each one in their own way by subjective viewpoint. However, it is difficult to search between a lot of subjective data for necessary and valuable tourism information. The purpose of our work was to gather objective information and subjective evaluation about tourism contents, and to develop a user adaptive tourism information website using a recommender system. Moreover, an exclusive weblog was developed as an interface for tourism information gathering.

  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, Technical report

In our simulation, tags, which are visible from each other, and there is no relation between the player's tag and the one's strategy firstly. The player's decision making is based on the partner's tag, and the player's strategy is evolved within the same tag members. We examine the effect of the difference in the rate, which is the number of the members having the same tag, and consider which is more advantageous between the minority group and majority one., The Institute of Electronics, Information and Communication Engineers, Japanese, Technical report

  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 recent years, it has been popular that economic and financial system is researched by multi-agent approach of Artificial Intelligence. The representative system is Artificial Market. Almost all of the researchers report the behavior of macro market prices constracted by micro trading agents who invest in single investment. But market participants in real Market make decision on plural investment outlets. If we extends a market model dealing plural investments, the market participants can make the portfolio dealing with the plural brands. Portfolio means the composition of assets.
