Outline of Final Research Achievements

Toward understanding the mechanism of social learning, the present study attempts to build computational model of bodily imitation as a basis for it. It is crucial to convert representation of bodily movements across sensory and motor systems and across self and other systems. The existing approach based the motor control theory requires sufficient information for controlling motor systems. It is, however, difficult to compute accurate mappings between sensory and motor systems on the basis of this existing theory, as it cannot have sufficient information on the other body. By exploiting the theoretical understanding that movements in different bodies can be identified on the basis of topological space of the dynamical systems, the present study proposes a computational theory of imitative learning based on the topological similarity of bodily movements.
