Abstract

The existing intrinsic reward gradually disappears as the agent continues to explore the environment, which makes the agent unable to use the intrinsic reward signal to guide the agent to find the optimal strategy. This paper proposed an intrinsic reward-based skill acquisition and combination approach to address this issue. The method firstly searched for a positive state in the interaction process between the agent and the environment, and selected the subgoal in the positive state. Secondly, it found the skill from a trajectory generated by the initial state to the subgoal and the subgoal to the termination state, and combined one or two or more subgoals in the skill. Finally, it used the skill to evaluate the distance from the initial state to the subgoal and the cumulative reward value from the initial state to the subgoal. The method achieves a high average reward value in the Mujoco environment, especially when the extrinsic reward is delayed. It shows that the subgoal and skills of the proposed method can effectively solve the problem that the agent cannot use the intrinsic reward signal to learn the optimal policy after the intrinsic reward disappears.
