English(EN) Action Shaping: Policies Absorb What They Can Express

新的行动塑造技术允许策略吸收可训练的偏移量

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-07 04:00

研究人员引入了一种名为行动塑造的新技术，该技术允许强化学习策略在训练期间吸收特定的偏移量，这些偏移量可以在部署时移除，而不会影响最优策略性能。该方法依赖于这样一个原理：如果策略自身的输出层能够精确地重现一个偏移量，那么该策略就可以吸收这个偏移量，这一概念被称为“可表达性”。行动塑造的有效性通过其在20个任务上的极低成本得到证明，偏移量的幅度表明了移除后潜在的性能下降。 AI

影响引入了一种改进强化学习策略训练和部署效率的新颖方法。

行动塑造：政策吸收其所能表达的内容

arXiv:2609.32752v2 Announce Type: replace Abstract: Reward shaping has a theorem: a potential-based term can be removed without changing the optimal policy. The same practice on the action channel, an offset added in training and dropped at deployment, has no theorem. Nothing can…
