Webb28 sep. 2024 · Keywords: Reinforcement Learning, Reward Shaping, Soft Policy Gradient. Abstract: Entropy regularization is a commonly used technique in reinforcement learning to improve exploration and cultivate a better pre-trained policy for later adaptation. Recent studies further show that the use of entropy regularization can smooth the optimization ... 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.
