The Behavioral Decision Model Estimation Research Group will conduct research on the construction and estimation of behavioral decision models that determine behaviors based on a robot's own experience and value judgment criteria. In order for a communicative robot to be accepted by society and coexist with people, the robot has to build a rapport with people belonging to that society. To develop such rapport, robots are required to behave consistently with their own intentions and purposes. This research group will achieve consistent behavior generation, using longitudinal data of daily behaviors and large-scale text data as the experience of the robot.

However, such rapport cannot be developed solely by persisting with the claims of the robot itself. For this reason, our research group tries to achieve the functions to estimate people’s behavioral decision models, with which the robot reconciles its own value judgments that affect its behaviors. These studies enable for robots to build rapport with people (the real purpose of communication), which leads to the realization of a society in which the robots establish symbiotic relationship with people.
