We provide a new non-asymptotic analysis of distributed temporal difference learning with linear function approximation. Our approach relies on “one-shot averaging,” where N agents run identical local copies of the TD(0) method and average the outcomes only once at the very end. We demonstrate a version of the linear time speedup phenomenon, where the convergence time of the distributed process is a factor of N faster than the convergence time of TD(0). This is the first result proving benefits from parallelism for temporal difference methods.
