A Motor Control Learning Model of Degrees of Freedom in Postural Control

Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we propose an efficient learning model that learns fast in a low dimensional state space using a low degrees of freedom (DOF) learning module at the first phase and after that, learns complicated movement in a higher dimensional state space by a high DOF learning module using the result of the low DOF module. To verify this model by a postural control problem, an upright posture was modeled with a two-link inverted pendulum. As a result of simulation applying this learning model, it was shown that this model learns more efficiently than simple reinforcement learning in the same DOF module.
