Abstract：Experience replay is to enable agents to learn and use past experience in the same strategy reinforcement learning.In the existing experience replay work,prioritized experience replay is based on TD error to divide the priority of experience for sam-pling,but this experience replay method does not take into account some important information about the difference between differ-ent states and target states in the experience.This paper proposes a method of experience replay,which is called goal oriented priori-tized experience replay.The results show that in OPENAI gym mountain_carv0,target oriented priority experience replay is superior to prioritized experience replay(PER)and random experience replay.This further shows that this method makes agents more effec-tive in the reinforcement learning process.
