Strings are concepts that generalize sequential data such as text, time series, labeled trees\/graphs, and 2D arrays. Our research interests are in designing fast and space-efficient algorithms for processing strings, with particular emphasis on their theoretical perspectives. Since the discovery of classical algorithms including KMP, suffix trees, and LZ compression, string algorithmics has been one of the most important sub-fields in theoretical computer science. Also in the real world, string algorithms are commonly utilized as core building blocks of information retrieval systems and data compression programs. Further, string-related problems are commonly seen in competitive programming contests. Our approach for tackling massive sequential data is first to reveal mathematical properties of strings using the theory of “word combinatorics\u201d, and then to develop advanced “algorithms and data structures\u201d techniques.<\/p>\n<\/div>\n

In the Laboratory of Intelligent Systems we create novel AI engines as well as build robust and adaptive intelligent systems. Current AIs can solve 19×19 versions of Go but behave poorly on easier 9×9 versions of the same game. Similarly, image recognition algorithms can reach 96% accuracy (supra-human) on tests and be fooled by only one pixel change. In other words, current AI lacks the robustness and adaptation present in even simple living beings. AI is based on engines that allows it to learn and reason over things, this lab builds novel engines based on different paradigms to reach high levels of robustness and adaptiveness intrinsically. Interestingly, by increasing the robustness and adaptiveness, other problems like Transfer Learning, One-Shot Learning would also be solved at the same time, igniting, possibly, a new age of intelligent systems.<\/p>\n<\/div>\n

    HumanoPhilic Systems Laboratory conducts research on cyber-physical systems (CPS: Cyber-Physical Systems) that support human life, by combining various information technologies, such as sensing from the real world, data processing in the cloud, and networking that conncts them. The term “HumanoPhilic” is the combination of “human” and “philic” which means having a high affinity.
    \nWe focus on human activity recognition using sensors (IoT) and machine learning (AI). Our research topics include both hardware development and software implementation. A major research issue is to explore what kind of sensors and algorithms can recognize the internal sate (Emotions and stresses) as well as the external state of a person (physical action). Furthermore, in recent years, as novel research beyond human activity recognition, we started focusing on a behavior change support system (BCSS). BCSS means information technologies that affect human future behavior.<\/p>\n<\/div>\n

    \"Human-centeredWe aim to study human-centered intelligence. To this end, we analyze real data under real situations and develop mechanisms to estimate, extract, and generate information users want and provide it to them when they need, considering their contexts, intentions, preferences, interests, and privacy issues. The projects we are conducting are roughly divided into four: 1) Text Mining and Message Generation, 2) Data Mining for Intelligent Transport Systems (ICT), 3) Educational Data Mining (EDM), and 4) Multi-modal Data Mining and Information Recommendation. For 1), we develop dialogue systems (Chat-bots) which automatically answer user queries, discriminating out-of-domain or out-of-intent queries with query augmentation techniques; we estimate user emotions; we study named entity recognition from patent documents and research papers, etc. For 2), we estimate city bus travel time, arrival time, and delay time, abnormal driving behaviors, and road situations by analyzing multi-modal ICT-related data such as vehicle probe data, obtained from ICT-devices (ETC 2.0 devices), dashboard camera data, weather-related data, traffic and human stream data, etc. For 3), we develop methods to estimate student learning situations and performance, to give automatic feedback analyzing student data such as student self-reflective comments freely-written after each lesson, e-learning logs etc., and to automatically score student short answers. Finally, for 4), we estimate recommended handcrafted works, which work will be bought in certain period of time, and who created the works, and track trends or changes of the works; we also estimate useful product review documents, and develop new collaborative filtering algorithms using Graph Convolutional Networks to extract useful information from user-item interactions. We have been having a joint operation system with the Humanophilic Systems Laboratory since 2020, which conducts
    \nresearch on cyber-physical systems being close to people, and been focusing on acquisition methods of various data.<\/p>\n<\/div>\n

    Human beings have social intelligence emerging in the world. For example, they estimate the tacit meaning of surrounding situations, learn in and from the context of real-world situations, and generate behavior adapted to their situations. However, little is known about the generation mechanism of this type of social intelligence. We are developing ubiquitous and multimodal sensing technologies to understand and enhance the mechanism of this type of social intelligence.<\/p>\n<\/div>\n

    Virtual Reality (VR) is a technology that extracts the essence of the real world and reproduces it beyond the constraints of time and space. In our lab, we are not only focused on recreating this essence but also on reconstructing it from diverse perspectives and values to create new senses of reality. The word “Hack” embodies our desire to express and create new realities that transcend established concepts and everyday conventions.
    \n\u3000Currently, we are particularly engaged in utilizing VR to transcend users from the physical constraints (such as weight and space) and conventional frameworks of the real world. Our research is divided into the following three units:<\/p>\n
