RIKEN Information R&D and Strategy Headquarters Behavior Learning Research Team

Team Leader: Yutaka Nakamura (D.Eng.)

Research Summary

Yutaka Nakamura (D.Eng.)

While humans engage in dialogue, they use not only language but also various modalities such as gestures. This team is measuring the participants' behaviors interacting with each other and modeling them using deep learning. We are also developing a framework for motion control of communication robots using the models obtained through learning. We are working on the following specific research topics:

  • Reinforcement learning for human robot interaction
  • Deep generative model for the behaviors during dialogue
  • Development of a control framework for communication robot
