Webb28 feb. 2024 · Hindsight Experience Replay (HER) is a simple yet effective idea to improve the signal extracted from the environment. Suppose we want our agent (a simulated robot, say) to reach a goal g, which is achieved if the configuration reaches the defined goal configuration within some tolerance. WebbThe hindsight experience replay augments the acquired experiences by replacing the goal with the goal measurement so that agent can use the data that reaches the replaced goal. Thus, the agent can be trained with meaningful rewards even if the agent does not reach the goal. To use a hindsight replay memory, set ExperienceBuffer of the agent … WebbHindsightExperienceReplayWrapper (replay_buffer, n_sampled_goal, goal_selection_strategy, wrapped_env) [source] ¶ Wrapper around a replay buffer in … dean harrison northwestern medicine

Webb5 juli 2024 · Dealing with sparse rewards is one of the biggest challenges in Reinforcement Learning (RL). We present a novel technique called Hindsight Experience Replay which allows sample-efficient learning from rewards which are sparse and binary and therefore avoid the need for complicated reward engineering.
