Abstract :
In this paper we represent a preliminary research on designing a behavior-based adaptive system utilizing self-optimizing memory controller. Rather than holistic search for the whole memory contents the model adopt associated feature analysis to successively memorize a newly experience state-action pair as an action of past experience, produce motor commands that make the controlled system to behave desirably in the future. Actor-critic learning is used to adaptively tuning the control parameters, while an on-line variant of random forests (RF) learner is used to approximate the policy of actor and the value function of critic. Learning capability of the proposed model is experimentally examined through a task of cart-pole balancing problem, designed in mind as computation with perception. The result shows that the robot with self-optimizing memory acquired behaviors such as balancing the pole, displays planning based on past experiences.
