WebHindsight experience replay (HER) has been shown an effective solution to handling sparse rewards with fixed goals. However, it does not account for dynamic goals in its vanilla form and, as a result, even degrades the performance of existing off-policy RL algorithms when the goal is changing over time. 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 …

We present a novel technique called Hindsight Experience Replay … WebTo check the ability of HER to deal with dynamic environments, we added this option to the bit flipping domain. This means that with every step the user makes, with probability 0.3, one of the goal's bits would flip, making it harder to predict. The goal's flipped bit is chosen with uniform probability.
