Faculty of Science and Technology

Department of
Information Sciences

Information science in the Department of Information Sciences is comprised of the 3 fields of "basic mathematical information," which handles "information" related to various nature, social and human phenomena in a mathematical manner with mathematics as the basis, "applied mathematical information," which handles basic mathematical information in a practical manner, and "computer science," which handles systems that process information; the aim of this department is to foster the ability to quantify information and carry out scientific analysis.

Research Groups & Research Areas

  • Basic Mathematical Information

    Huge volumes of various types of information are overflowing like a flood. How should we quantify and scientifically handle such a huge amount of information? Basic Mathematical Information measures the uncertainty, size, value, etc. of "information" as information quantities, and deals with how "information" is expressed mathematically.

  • Applied Mathematical Information

    We formulate problems related to "information" of a phenomenon such as found in nature, society or human beings, mathematically create a hypothesis (model/principle) of the phenomenon, and construct a theory of a method or technique for a mathematical analysis based on the "information" and the "information amount". In this way, we infer the optimal solution, dealing with how to solve and improve practical problems in various fields.

  • Computer Science

    To actually process large volumes of "information", we need the assistance of a computer. Further, information needs to be processed by a computer also in order to infer an optimal solution for mathematical models of various phenomena by use of mathematical analysis methods. Computer Science deals with systems for processing this information.
