Value Explicit Pretraining learns transferable representations for reinforcement learning agents

Researchers have developed Value Explicit Pretraining (VEP), a novel method designed to improve the transferability of representations in visual reinforcement learning. VEP utilizes suboptimal, unlabeled demonstration data to train an encoder that learns representations invariant to environmental dynamics and appearance changes. This approach allows for more efficient learning of new tasks that share similar objectives with previously encountered tasks. Experiments on various benchmarks, including Ant locomotion, a navigation simulator, and Atari games, demonstrate that VEP significantly outperforms existing pretraining methods in generalization to unseen tasks, achieving up to a twofold improvement in rewards and threefold improvement in sample efficiency.
