RIKEN Center for Advanced Intelligence Project Structured Learning Team
Team Leader: Yoshinobu Kawahara (D.Eng.)
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
- Development of optimization algorithms for efficient learning
- Learning for analysis of spatiotemporal dynamics
- Application of developed methods to scientific and engineering data
