Computer Science

Today is the Age of Information, which is characterized by the contributions made by the Internet and multimedia. In this society, the development of techniques relating to information technology promotes the advancement of the information oriented society, and as a result this society demands the cultivation of the most up-to-date techniques in information technology. Thus both information technology and the resulting society accelerate each other’s development. In this course, we aim to cultivate experts who lead the field in information technology and its society, both of which are in rapid advancement. Therefore in this course we intend to conduct training in ultra-modern fields in computer science based upon knowledge and techniques obtained at the undergraduate level and centered on a basis of information technology. There are three major divisions in this course : Computer Systems, Artificial Intelligence and Applied Computer Science, all of which conduct up-to-date research and training in order to cultivate creative engineers.
