Dr. Ichiro Kobayashi is a Professor in the Department of Information Sciences at Ochanomizu University. He has been studying for more than 30 years in the areas of Information Sciences, especially Machine Learning-based Artificial Intelligence and Natural Language Processing.

Research Interests / Areas

Linguistic information processing, intelligent information processing, verbalization, decoding of brain information, latent semantic analysis, text processing, robotics.

Research Contents

I am interested in using artificial intelligence and language information processing techniques to make the target system more intelligent. In addition, I am actively developing methods to explain time-series data in words and methods to decode information in the brain. In the field of natural language processing, we are conducting latent semantic analysis of documents, and based on this information, we are conducting research on multiple document summarization, document classification, and information retrieval. We are also studying robot control using evolutionary computation and reinforcement learning.
