arXiv:2605.08253v2 Announce Type: replace Abstract: Distributional reinforcement learning (DRL) models the full return distribution, but existing finite-support or quantile-based methods rely on projections, while recent flow-based approaches can suffer from \emph{boundary mismatch} at the flow source or from \emph{high-variance} bootstrapping when current and successor noises are independent. We propose Path-Coupled Bellman Flows (PCBF), a continuous-time DRL method that learns return distributions with flow matching using \textbf{source-consistent Bellman-coupled paths}: the current path sta
The paper addresses current limitations in distributional reinforcement learning (DRL) methods, specifically boundary mismatch and high-variance bootstrapping, indicating ongoing research advancement in foundational AI techniques.
Improved DRL methods could lead to more robust and reliable AI agents capable of learning complex tasks with a better understanding of uncertainty, which is crucial for real-world applications.
The proposed 'Path-Coupled Bellman Flows' method introduces a new continuous-time approach that aims to overcome known issues in existing DRL techniques, potentially making DRL more effective and widely applicable.
