WebbAbstract. We study the effect of baselines in on-policy stochastic policy gradient optimization, and close the gap between the theory and practice of policy optimization methods. Our first contribution is to show that the \emph {state value} baseline allows on-policy stochastic \emph {natural} policy gradient (NPG) to converge to a globally ...
