Abstract
A policy improvement method of improving a policy of reinforcement learning based on a state value function is performed by a computer. The method causes a computer to execute a process including: calculating an input to a control target based on the policy and a predetermined exploration method of exploring for an input to the control target in the reinforcement learning; and updating a parameter of the policy based on a result of applying the calculated input to the control target, using the input to the control target and a generalized inverse matrix regarding a state of the control target.
