Webb27 feb. 2024 · While shaped rewards can increase learning speed in the original training environment, when the reward is deployed at test-time on environments with varying dynamics, it may no longer produce optimal behaviors. In this post, we introduce adversarial inverse reinforcement learning (AIRL) that attempts to address this issue. … WebbHowever, an important drawback of reward shaping is that agents sometimes learn to optimize the shaped reward instead of the true objective. In this report, we present a novel technique that we call action guidance that successfully trains agents to eventually optimize the true objective in games with sparse rewards yet does not lose the sampling …
