本文提出基于 FiLM 条件化的 RND 反探索方法,解决离线强化学习中分布外动作惩罚问题,在 D4RL 上性能媲美集成方法且大幅优于无集成方法。
摘要:
尽管 Random Network Distillation(RND)在多个领域取得了成功,但研究表明其作为不确定性估计器不足以惩罚离线强化学习中的分布外动作。本文重新审视这些结果,发现若对 RND 先验采用朴素的条件化选择,actor 将无法有效最小化反探索奖励,而判别性并非问题所在。我们证明,基于 Feature-wise Linear Modulation(FiLM)的条件化可避免这一局限,从而得到一种简单高效的、无需集成的 Soft Actor-Critic 算法。我们在 D4RL 基准上进行评估,结果表明其性能可与基于集成的方法相当,并大幅优于无需集成的方法。
英文摘要:
Despite the success of Random Network Distillation (RND) in various domains, it was shown as not discriminative enough to be used as an uncertainty estimator for penalizing out-of-distribution actions in offline reinforcement learning. In this paper, we revisit these results and show that, with a naive choice of conditioning for the RND prior, it becomes infeasible for the actor to effectively minimize the anti-exploration bonus and discriminativity is not an issue. We show that this limitation can be avoided with conditioning based on Feature-wise Linear Modulation (FiLM), resulting in a simple and efficient ensemble-free algorithm based on Soft Actor-Critic. We evaluate it on the D4RL benchmark, showing that it is capable of achieving performance comparable to ensemble-based methods and outperforming ensemble-free approaches by a wide margin.
