Abstract: The effectiveness of reinforcement learning (RL) agents in continuous control robotics tasks is heavily dependent on the design of the underlying reward function. However, a misalignment between the reward function and user intentions, values, or social norms can be catastrophic in the real world. Current methods to mitigate this misalignment work by learning reward functions from human preferences; however, they inadvertently introduce a risk of reward overoptimization. In this work, we address this challenge by …
