arXiv:2607.08444v1 Announce Type: cross Abstract: In this paper, we study quantile-based distributional reinforcement learning from the perspective of statistical efficiency. We focus on distributional policy evaluation, whose goal is to characterize the return distribution, namely the distribution of discounted cumulative rewards under a given policy. To obtain a finite-dimensional representation of the return distribution, we consider the quantile fixed point $\eta_m$ induced by the quantile-projected distributional Bellman equation. Assuming access to a generative model, we construct an est
This paper represents a refinement in the theoretical underpinnings of distributional reinforcement learning, a field seeing accelerated research due to increasing computational capabilities and interest in AI agents.
Improved statistical efficiency and inference methods for distributional reinforcement learning are critical for developing more robust and reliable AI systems, especially those operating in complex, real-world environments.
The theoretical advancements could lead to more stable and performant AI agents that better understand risk and uncertainty, rather than just expected returns.
