Information Sciences

Japanese / English  

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.

Discrete Mathematics / Document Processing System iFormula Processing Special Course j
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.

Information Visualization / Multimedia iVisual Computing Special Course / Media Computing Special Course j
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.)

Network Computing / Middleware (Computer Network Special Course)
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.
Tetsuya Kawamura(Prof.)

Numeric Hydrodynamics Special Course / Numeric Simulation iSimulation Science Special Course j
In our laboratory, we analyze the issues of Science and Engineering by numeric simulations. In recent years, the long progress of computer has made numeric simulations an immerse possibility as the third way of study next to theories and experiments. In particular, we have interests in applying numeric simulations to Environmental Science and Life Science, since the environmental issues are more and more vital today.
Ichiro Kobayashi(Prof.)

Intellectual Information Processing iLinguistic Information Processing j
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.
Itiro Siio(Prof.)
Lab Home Page
Human Interface iHuman Computer System Special Course)
We make approaches and implementations of human interface and application in a field more accessible to us, such as home information appliances and ubiquitous computers for daily use. It is needless to say that small-scale and low-cost computer technology should be a device that is close to our daily lives.

Applied Analysis /Operator Algebra Theory (Information Analysis Special Course)
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.
Kenichi Asai(Associate Prof.)
Lab Home Page
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.
Masatsu Kasukawa(Associate Prof.)

Computer Architecture iComputer Architecture Special Course j
Our focus is on input devises such as keyboard and mouse, and securities such as recognition and steganography. Our lab is surrounded by various kinds of measuring equipments and machine tools.

Numerical Computation / Statistical Mechanics (Numerical Method Special Course)
Macroscopic properties of a system are different from those of microscopic individuals. Statistical mechanics has been developed to study interesting macroscopic phenomena. We use numerical methods to study those phenomena.
Daisuke Bekki (Associate Prof.)

Computational Linguistics / Theoretical Linguistics iMathematical Science Special Course j
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.

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.

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."

Meteorology / Physical Climatology / Atmosphere-ocean data analysis
In response to sunlight, why do air and sea water attracted by a rotating sphere with a radius of 6,000 km generate rich natural phenomena, such as heavy rainfall, typhoons, and El Nino events? To make a step forward in answering this question, we employ physical mathematics, data analysis and simulations, and write research articles in English to share our thoughts with the world. Here we also tackle social issues, such as global warming and extreme weather, from the viewpoint of information sciences.
