新的乐观策略正则化提升了RL智能体在Atari游戏上的性能

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-23 04:00

研究人员推出了一种新颖的方法——乐观策略正则化（OPR），通过将罕见的、高回报的 эпизоды 作为奖励加成来增强强化学习智能体。该技术是对近端策略优化（PPO）的一个简单修改，不需要辅助网络或复杂的循环。在对49款Atari游戏的实验中，OPR实现了148.4%的中位数人类归一化分数，决策次数显著少于基线方法，在大多数游戏上均优于已发布的PPO结果。 AI

影响该方法有望提高强化学习智能体的训练效率，尤其是在奖励稀疏的环境中。

Optimistic Policy Regularization: Elite-Statistic Reward Shaping

arXiv:2603.06793v2 Announce Type: replace Abstract: On-policy agents discard trajectories after each update, including rare high-return episodes. We propose Optimistic Policy Regularization (OPR), which turns those episodes into a closed-form reward bonus: we estimate an elite ac…
