Scientific journal - Phantom in the opera: adversarial music attack for robot dialogue system
Sheng Li; Jiyi Li; Yang Cao
Frontiers in Computer Science, 6, Frontiers Media SA, 15 Feb. 2024
Scientific journal, This study explores the vulnerability of robot dialogue systems' automatic speech recognition (ASR) module to adversarial music attacks. Specifically, we explore music as a natural camouflage for such attacks. We propose a novel method to hide ghost speech commands in a music clip by slightly perturbing its raw waveform. We apply our attack on an industry-popular ASR model, namely the time-delay neural network (TDNN), widely used for speech and speaker recognition. Our experiment demonstrates that adversarial music crafted by our attack can easily mislead industry-level TDNN models into picking up ghost commands with high success rates. However, it sounds no different from the original music to the human ear. This reveals a serious threat by adversarial music to robot dialogue systems, calling for effective defenses against such stealthy attacks. - Human-LLM Hybrid Text Answer Aggregation for Crowd Annotations.

English, Scientific journal, Paraphrase identification has been one of the major topics in Natural Language Processing (NLP). However, how to interpret a diversity of contexts such as lexical and semantic information within a sentence as relevant features is still an open problem. This paper addresses the problem and presents an approach for leveraging contextual features with a neural-based learning model. Our Lexical, Syntactic, and Sentential Encodings (LSSE) learning model incorporates Relational Graph Convolutional Networks (R-GCNs) to make use of different features from local contexts, i.e., word encoding, position encoding, and full dependency structures. By utilizing the hidden states obtained by the R-GCNs as well as lexical and sentential encodings by Bidirectional Encoder Representations from Transformers (BERT), our model learns the contextual similarity between sentences effectively. The experimental results by using the two benchmark datasets, Microsoft Research Paraphrase Corpus (MRPC) and Quora Question Pairs (QQP) show that the improvement compared with the baseline, BERT sentential encodings model, was 1.7% F1-score on MRPC and 1.0% F1-score on QQP. Moreover, we verified that the combination of position encoding and syntactic features contributes to performance improvement. - English and Chinese Neural Metonymy Recognition Based on Semantic Priority Interruption Theory

English, With the recent rapid growth of social image hosting websites, such as Flickr, it is easier to construct a large database with social tagged images. We propose an unsupervised approach for automatic ranking social images to improve content-based social image retrieval. We construct an image-tag relationship graph model with both social images and tags. The approach extracts visual and textual information and combines them for ranking by propagating them through the graph links with an optimized mutual reinforcement process. We conduct experiments showing that our approach can successfully use social tags for ranking and improving content-based social image search results, and performs better than other approaches. - Improving Content-based Social Image Retrieval based on an Image-Tag Relationship Model

English, Social image hosting websites, such as Flickr, have a rapid growth recently. Content based image retrieval on such websites is an useful potential service but is still unavailable because its performance is unsatisfactory. We propose a multi modal relevance feedback (MMRF) scheme and a supervised re-ranking approach based on it to improve the performance for practical application. Our multi modal scheme utilizes both image and social tag relevance feedback instances. The approach propagates visual and textual information as well as multi modal relevance feedback information on the graph with a mutual reinforcement process. We conduct experiments based on real world data from Flickr to evaluate the performance of our approach. We also conduct an experiment to show that our multi modal relevance feedback scheme significantly improves performance compared with traditional single modal relevance feedback (SMRF) scheme. - Ranking Content-Based Social Images Search Results with Social Tags

インターネットの急速な普及により,多数のアプリケーションを用い,ウェブ・ソースから膨大な量の情報を自動的,かつ容易に収集することが可能となった.このことを背景に,近年,データマイニング,検索,及び解析技術に関する社会からの要請は,急速に増している.一方で,データの解析はそのデータが利用されている社会や文化的背景を無視し記号列として解析されることが多いため,正しく解析できず,結果的に実用的な知識として使用できない問題が生じている.本研究交流では,南開大学が実施している理論に基づくデータ解析法,及び山梨大学が実施している実データに基づく解析技術に関する学生間の研究交流を通し,将来的にデータ解析において若い世代が国際的に活躍できる優秀な人材の育成に努めることを目的とする.
