A lab that uses computers to calculate mathematical expressions and solve wasan (traditional Japanese mathematics) geometry problems.

The Computer Algebra Lab studies computer algebra, which is the algorithms for handling mathematical expressions on computers, and its applications. One application is research that revisits computational geometry problems from wasan (traditional Japanese mathematics) and solves them again with modern computer algebra. For example, for polygons inscribed in a circle, the lab derives by computation formulas that express the radius and area of the circumscribed circle in terms of the side lengths. In the course "Theory of Computer Algebra Systems" in the School of Informatics, College of Media Arts, Science and Technology, students learn algebraic computation algorithms using computer algebra software, and their application to computational geometry.

A lab that uses metadata to manage and preserve information resources on the internet.

The Metadata Lab works on research using metadata in order to distribute and manage the wide variety of information resources on the internet. Metadata is "data about data," and the lab's website explains it by comparing it to the label on a can. The lab aims to attach metadata to digital content so that its contents remain understandable one year, ten years, and 100 years from now, making access and management easy. The lab welcomes students who are interested in the idea of "getting hands-on and making something!" Students who want to be assigned to the lab must have an interview with a faculty member.

A lab that designs hybrid intelligence, which combines human and AI knowledge.

The Hybrid Intelligence Design Lab aims to establish a science and technology of designing "hybrid intelligence," which combines AI, humans, and big data. The lab's stated goal is to solve difficult problems facing humanity, such as disaster prevention, health, education, the environment, hunger, and poverty, by bringing together the intelligence of people and computers. Led by its students, the lab develops Crowd4U, a crowdsourcing platform, and carries out research that uses it. The lab's website also introduces it under the name "Morishima-Ito Lab."

A lab that explores the mechanisms of databases and information retrieval.

The Data Systems Engineering Lab studies implementation technologies for next-generation database systems, as well as theory and applications that support information retrieval. Its listed research areas are database systems, knowledge base systems, educational systems in networked environments, information retrieval, and knowledge discovery. The faculty's research topics include efficient search methods for high-dimensional data, structuring information based on conceptual relationships, and knowledge discovery. In the College of Media Arts, Science and Technology, the lab is listed under the field "information management, sharing, retrieval, and discovery on network media."

A lab that explores how language comes to be by studying communication between AI agents.

The Multi-Agent Learning and Language Understanding Lab researches the question "what exactly is language?" from a computational perspective. Within the framework of multi-agent reinforcement learning, the lab builds systems in which multiple machine-learning agents acquire communication from scratch, and analyzes the conditions and mechanisms under which it becomes language-like. As ways of approaching this question, the lab also studies learning methods that promote the establishment of cooperation and norms, and methods for interpreting the internal mechanisms of AI. In April 2026, the lab changed its name from "Machine Learning and Language Understanding Lab" to "Multi-Agent Learning and Language Understanding Lab." For graduation research, the lab accepts students from the College of Media Arts, Science and Technology and the College of Knowledge and Library Sciences.

The lab brings together the power of people and AI through crowdsourcing.

The Fusion Intelligence Design Lab researches "fusion intelligence," which combines AI, humans, and big data. By combining billions of people accessible through the network with AI such as machine learning, the lab works on problems that could not be solved before. Led by students, the lab develops Crowd4U, a crowdsourcing platform, and conducts research using it. Students can choose their research theme in the way that suits them: taking over an existing project, being assigned a new one, or proposing their own.

The lab explores content expression through graphic design and CG.

The Graphic Design Lab researches graphic methods based on visual communication. It focuses on why something looks beautiful, where its appeal lies, and what devices were used to express it. Combining art and design skills with cutting-edge technology, the lab produces content. Professor Sangtae Kim has a track record of joint projects with the fields of medicine, engineering, and art, as well as joint research with NTT.

The lab analyzes and explores the relationship between people and sound and music.

The Human and Sound Informatics Lab researches interdisciplinary areas centered on sound and music, such as sound synthesis, cognition, emotion, and sound environments. Both research that analyzes music and sound themselves and research on the relationship between people and music and sound are carried out. The faculty study timbre, singing voice, hearing impairment and music, and instrument performance and knowledge representation. Students doing graduation research are accepted from the College of Media Arts, Science and Technology, and graduate students from the Degree Program in Informatics of the Graduate School of Comprehensive Human Sciences.

A lab that uses ultrasound, VR, and AI to pursue an ecosystem in which humans and computers coexist.

The Digital Nature Lab conducts research with an eye toward the arrival of "Digital Nature" beyond ubiquitous computing. Digital Nature is a view of nature from the perspective of computer science, which treats everything, including both humans and computers, as computable, autonomous nature. Using the methods of computer science, the lab implements the options that computer applications create between the material world and the virtual world, and takes on problem solving in industry, academia, and the arts. On the lab's website, it is introduced under the name "Digital Nature Lab".
