Shaped reward
Webb4 nov. 2024 · We introduce a simple and effective model-free method to learn from shaped distance-to-goal rewards on tasks where success depends on reaching a goal state. Our … Webb本文设计了一种 shaped rewards 用于平衡探索与利用，本文是在 Goal-Conditional Policy的环境中提出的。 这种环境面临的问题是，一般而言只有到达当智能体到达目标后可以有明确的奖励信息，但是这种奖励很稀疏，使得RL算法难以学习。 在此之前有一些方法能够解决该问题，例如 Hindsight Experience Replay，参看： 本文提出了另一种方法可以使智能体 …

WebbSummary and Contributions: Reward shaping is a way of using domain knowledge to speed up convergence of reinforcement learning algorithms. Shaping rewards designed by domain experts are not always accurate, and they can hurt performance or at least provide only limited improvement.
