Summary: This paper introduces a method called hindsight experience replay (HER), which is designed to improve performance in sparse reward, RL tasks. The basic idea is to recognize that although a trajectory through the state-space might fail to find a particular goal, we can imagine that the trajectory ended at some other goal ...
WebbHindsight Experience Replay (HER) HER is a method wrapper that works with Off policy methods (DQN, SAC, TD3 and DDPG for example). Note. HER was re-implemented from scratch in Stable-Baselines compared to the original OpenAI baselines. WebbTrain a reinforcement learning agent in a navigation environment with sparse rewards.
