We presented the paper “ReCePS: Reward Certification for Policy Smoothed Reinforcement Learning”, at the AAAI Conference on Artificial Intelligence (AAAI 2024). Our work introduces a certification method for smoothed policies, which are more robust than traditional policies in reinforcement learning. We presented a more general certification method than the previous state-of-the-art, using a black-box approach. Our paper is freely available. The source code is also available.
