Shaped reward
WebbThe second is shaped rewards which are designed specifically to make the task easier to learn by introducing biases in the learning process. The inductive bias which shaped rewards introduce is problematic for emergent language experimentation because it biases the object of study: the emergent language. The fact that shaped rewards are ... 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 ...

Webb24 nov. 2024 · Mastering robotic manipulation skills through reinforcement learning (RL) typically requires the design of shaped reward functions. Recent developments in this area have demonstrated that using sparse rewards, i.e. rewarding the agent only when the task has been successfully completed, can lead to better policies. However, state-action … WebbA good shaped reward achieves a nice balance between letting the agent find the sparse reward and being too shaped (so the agent learns to just maximize the shaped reward), …
