arXiv:2606.08602v1 Announce Type: new Abstract: We present an online reinforcement learning (RL) algorithm for fine-tuning flow-matching policies in continuous-control problems. Our key insight is to view RL-based policy improvement as a transport of action densities towards regions of high reward, which naturally aligns with the transport formulation of flow matching models. Prior methods either approximate the current or optimal policy distribution or resort to distillation, which introduces biased gradients or sacrifices multimodal modeling capacity. In contrast, our approach for RL with De
The continuous development in reinforcement learning and the alignment of flow-matching models with density transport problems are driving this innovation now.
This development proposes a more robust and less biased method for fine-tuning AI policies, potentially leading to significant advancements in general-purpose AI and autonomous systems.
Existing methods that approximate policy distributions or rely on distillation, which introduce bias or sacrifice modeling capacity, are challenged by this new approach.
