arXiv:2606.25593v1 Announce Type: new Abstract: We study optimal-policy geometry in structured Markov decision processes. While approximate dynamic programming and reinforcement learning typically approximate high-dimensional value functions, we show that optimal policies induce simpler decision tessellations. We propose boundary-based policy approximations that learn policy regions directly. A policy-loss decomposition links performance degradation to action margins and explains why errors concentrate near indifference boundaries. Inventory control and queue admission experiments show lower p
This research, published in 2026, presents a novel approach in AI policy approximation, indicating an ongoing refinement in methods for autonomous decision-making systems.
Improved policy approximation without high-dimensional value functions could make AI agents more efficient and practical, enabling wider deployment in complex real-world scenarios.
The focus shifts from approximating complex value functions to directly learning simpler policy regions, potentially leading to more robust and explainable AI control in dynamic systems.
