Webb22 mars 2024 · 下面是HER的算法，简单地解释一下就是：利用当前policy在环境中交互获得 trajectory τ ，然后将 (s, a, r (a, s, g), s’, g) 存储在 replay buffer 中，然后再挑选一些其他的 goal 对这个 trajectory τ 中的 g 和 r 做修改，然后存储在r eplay buffer 中，之后就是普通的基于replay buffer 算法中常见的从 buffer 中 sample，然后训练等过程中。 那么关 … WebbI dag · 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, …
WebbRecent works have shown that using expressive policy function approximators and conditioning on future trajectory information -- such as future states in hindsight experience replay (HER) or returns-to-go in Decision Transformer (DT) -- enables efficient learning of context-conditioned policies, where at times online RL can be fully replaced … WebbI dag · Learning from demonstrations (LfD) is an important technique to help reinforcement learning (RL) boost the training process, especially in the case of sparse rewards. But a major obstacle is the acquisition of expert demonstrations, which is …
