A Diffusion Approximation for Temporal-Difference Learning with Linear Features under Markovian Noise
arXiv:2606.18183v1 Announce Type: cross Abstract: Temporal difference (TD) learning with linear function approximation is a core method for policy evaluation. Its classical continuous-time description is an ordinary differential equation (ODE), which captures the asymptotic mean dynamics but neglects stochastic fluctuations determining the error floor. We introduce a stochastic differential equation (SDE) approximation for linear TD(0) under Markovian noise. The resulting model distinguishes the contraction dynamics governed by the projected Bellman operator from the influence of Markovian sam
This research from 2026 improves our theoretical understanding of fundamental AI learning algorithms, which is crucial as these systems become more complex and widespread.
A deeper understanding of TD learning's stochastic behavior can lead to more robust, efficient, and reliable AI systems, especially in areas requiring real-time adaptation and uncertainty management.
This SDE approximation refines the mathematical models used to predict and control the learning dynamics of AI, moving beyond asymptotic mean behaviors to account for stochastic fluctuations.
