WebAug 17, 2024 · Hindsight experience replay (HER) [] was proposed to improve the learning efficiency of goal-oriented RL agents in sparse reward settings: when past experience is replayed to train the agent, the desired goal is replaced (in “hindsight”) with the achieved goal, generating many positive experiences. In the above example, the …
