Admission Policy (Master's Program in Computer Science)

Information Science is a fast progressing field of study. In order to cultivate future researchers who will lead the way, highly-specialized professionals, and educators of the next generation, we offer wide research and educational opportunities from basic principles to applied technology. We therefore welcome highly-motivated persons with basic academic skills in Information Science and Mathematical Science, and those with sophisticated English academic literacy.

Programming Languages (Advanced Topics on Programming Languages)
We study the fundamental theory of programming languages, focusing on functional languages in particular. How can we execute a program efficiently? How can we write a program easily? How can we avoid programming errors? We approach the structure and essence of programming languages using mathematical approaches.
Noriko Asamoto (Prof.)
Lab Home Page
Discrete Mathematics / Document Processing System (Advanced Formula Processing)
We take a computational approach in analyzing natural and social phenomena. For example, applied studies of understanding phenomenon of formula processing, and a supportive use of computing machine in a process of knowledge acquisition. Also a use of computing machine and network especially in a field of education, particular in remote education.
Takayuki Itoh (Prof.)
Lab Home Page
Information Visualization / Advanced Multimedia (Visual Computing / Advanced Media Computing)
We are involved in the visualization of information using computer graphics to contribute to our society. For example, visualization in the fields of electric power, medicine, medical care, life information, and security. We study how to use visualization to work on multimedia technology as graphics and audio data.
Masato Oguchi (Prof.)
Lab Home Page
Network Computing / Middleware (Advanced Computer Network / Distributed Computing)
We study advanced use of networks in data processing, providing information, supportive systems in user communication. Computer network, represented as internet, is requisite and considerable as a social infrastructure in all computer use. Thus, we must investigate the tremendous upgrade and continuing advance of technology.
Kazue Kudo (Prof.)
Lab Home Page
Quantum Software / Statistical Physics (Advanced Numerical Method)
Quantum software studies computational methods and applications that make use of quantum computers and quantum-inspired devices. We use quantum information technology to solve problems efficiently, such as optimization problems, and to enhance artificial intelligence.
Ichiro Kobayashi (Prof.)
Lab Home Page
Intellectual Information Processing (Linguistic Information Processing)
Our study is about the computer technology of intellectual processing and of understanding human language. Our aim is to communicate with robots so that future robots can work with us in our daily lives.
Daisuke Bekki (Prof.)

Computational Linguistics / Theoretical Linguistics (Advanced Mathematical Science)
My research project targets on formal and computational linguistics, in particular, syntactic and semantic structures. One of the esoteric facts about natural language is that almost all of us competently use it without being able to explain how it is processed. Our approach toward this fundamental question is two-fold: construction of a formal theory of natural language based on mathematical logic, and generalization of language phenomena that are repeatable among native speakers.

Applied Analysis /Operator Algebra Theory (Advanced Information Analysis)
It might sound unfamiliar, but my specialty is Anti-commutative Probability Theory (something different to Probability Theory). For a masteral research, we study the methods and applications of statistical data analysis that extract genuinely valuable information from the static-ridden data.
Yuki Igarashi (Associate Professor)
Laboratory HomePage
Human Interface (Advanced Human Computer System)
We study HCI technology for future computers that can be used by anyone in their living space. We also study assistive technologies for novices using graphical representations.
Hieu Hanh Le (Associate Prof.)
Lab Home Page
Database/Data Engineering (Advanced Database)
There is a strong demand for technologies that reliably integrate a wide variety of large amounts of data, extract the necessary information from it, and make effective and useful use of it. Therefore, we are conducting research on practically useful methods, focusing on information storage and retrieval technologies. For example, we have worked on highly reliable power proportional storage systems considering both performance and power consumption, performance improvement of database systems, and medical practice recommendation based on analysis of electronic medical records, etc.

Molecular programming / evolutionary optimization
While nowadays computers are usually silicon-based, the concept of computing, as proposed by Alan Turing, is more generic. We focus on molecular programming, a field that relies on encoding data as molecular concentrations and operations as chemical reactions among those molecules.
The main issue is programmability: how to turn a given program into a valid set of reactions implementing it? We combine two approaches: computer assistance for human-based designs and evolutionary optimization for automated design discovery.
Tsubasa Kohyama(Lecturer)
Lab Home Page
Meteorology / Physical Climatology / Atmosphere-ocean data analysis
What are the factors and mechanisms that determine the weather and climate on Earth as we know it? We answer this question from the viewpoint of applied mathematics and information sciences.
Atsuki Nagao (Lecturer)
Lab Home Page
Discrete Algorithms/ Computational Complexity
On computer science, we always face the challenge to reduce resources such as computation time or memories. For this challenge, it is one approach that constructing more efficient, approximate, or stochastic algorithms. There is also another approach that proving the lower bound, say, "there is no more efficient algorithm than we know."
