RIKEN Center for Advanced Intelligence Project Structured Learning Team
Team Director: Yoshinobu Kawahara (D.Eng.)
Research Summary
When making predictions based on intelligent information processing such as machine learning, we usually have prior information about structures among variables in data. In our team, we study theories and algorithms for learning with such structural information. Moreover, we conduct applied researches by applying developed algorithms to a variety of scientific and engineering data.

- Machine learning with structural prior information
- Machine learning for analysis, prediction and control of complex dynamics
- Application of developed methods to scientific and engineering data
