Researchers have developed a new approach for linear TD(0) algorithms that utilizes Polyak--Ruppert averaging. This method achieves both robust, curvature-free convergence rates and fast, curvature-dependent rates simultaneously. The technique relies on a novel toolkit for analyzing geometrically mixing Markov chains, which decomposes Markov noise into a martingale term and a controlled remainder, enabling a new self-bounding inductive argument for pathwise stability.
