研究人员开发了新的强化学习策略方法，旨在提高效率和表达能力。一种方法，基于分数的一次性均值流策略优化（SOM），使用Q函数分数和概率流ODE构建目标速度场，通过减少训练和推理时间，在在线强化学习中实现了最先进的性能。另一项开发，随机均值流策略（SMFP），提供了一个一次性生成策略类别，通过均值流变换将噪声映射到动作，为离策略设置中稳定和探索性的策略改进提供了统一的目标。 AI
影响 这些新的策略优化技术有望加快强化学习的训练和推理速度，从而可能加速机器人和自主系统的进步。

arXiv:2605.21282v2 Announce Type: cross Abstract: Online off-policy reinforcement learning (RL) is shaped by two coupled choices: the policy class and the update rule. Gaussian policies are fast and have tractable entropy, but struggle with multimodal action distributions. Genera…
