Webbhindsight experience replay (HER) (Andrychowicz et al., 2024) from goal-conditioned rein-forcement learning to theorem proving. The core idea of HER is to take any “unsuccessful” trajectory in a goal-based task and convert it into a successful one by treating the ﬁnal state as if it were the goal state, in hindsight. 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. mildred clarkeWebbThe 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 … mildred clary obituary
