Sample-Efficient Preference-based Reinforcement Learning with Dynamics Aware Rewards

Abstract (arXiv)

Preference-based reinforcement learning (PbRL) aligns a robot behavior with human preferences via a reward function learned from binary feedback over agent behaviors. We show that dynamics-aware reward functions improve the sample efficiency of PbRL by an order of magnitude. In our experiments we iterate between: (1) learning a dynamics-aware state-action representation (zsa) via a self-supervised temporal consistency task, and (2) bootstrapping the preference-based reward function from (zsa), which results in faster policy learning and better final policy performance. For example, on quadruped-walk, walker-walk, and cheetah-run, with 50 preference labels we achieve the same performance as existing approaches with 500 preference labels, and we recover 83% and 66% of ground truth reward policy performance versus only 38% and 21%. The performance gains demonstrate the benefits of explicitly learning a dynamics-aware reward model. Repo: texttthttps://github.com/apple/ml-reed.
