归一化流实现参数高效的分布强化学习

研究人员开发了NFDRL,一种用于分布强化学习的新型架构,它利用连续归一化流来建模回报分布。与现有的分类或分位数方法相比,这种方法提供了更参数高效的手段,因为其模型大小不会随着分布所需分辨率的增加而增加。该系统采用几何感知Cramér代理进行训练,确保了真实的概率度量和无偏的样本梯度,这些特性是先前方法并非总是同时实现的。实证结果表明,NFDRL能够捕捉复杂的回报景观,并在Atari-5基准测试中取得与现有基线相当的性能。 AI

影响 引入了一种更参数高效的在强化学习中建模回报分布的方法,有可能用更少的资源实现更复杂的模拟。

    参数高效分布强化学习:基于归一化流和几何感知Cram\'er代理

    arXiv:2505.04310v2 Announce Type: replace-cross Abstract: Distributional Reinforcement Learning (DistRL) improves upon expectation-based methods by modeling full return distributions, but standard approaches often remain far from parsimonious. Categorical methods (e.g., C51) rely…
