Dynamic hindsight experience replay
WebJul 5, 2024 · In particular, we run experiments on three different tasks: pushing, sliding, and pick-and-place, in each case using only binary rewards indicating whether or not the task is completed. Our ablation studies show that Hindsight Experience Replay is a crucial ingredient which makes training possible in these challenging environments.

Web12 hours ago · Sparse rewards is a tricky problem in reinforcement learning and reward shaping is commonly used to solve the problem of sparse rewards in specific tasks, but it often requires priori knowledge and manually designing rewards, which are costly in many cases. Hindsight... WebUsing hindsight experience replay. Hindsight experience replay was introduced by OpenAI as a method to deal with sparse rewards, but the algorithm has also been shown to successfully generalize across tasks due in part to the novel mechanism by which HER works. The analogy used to explain HER is a game of shuffleboard, the object of which is …
