PI2 is a recent example of this approach. It combines a derivation from first principles of stochastic optimal control with tools from statistical estimation theory. In this paper, we consider PI2- as a member of the wider family of methods which share the concept of probability-weighted averaging to iteratively update parameters to optimize a cost function. At the conceptual level, we compare PI2 to other members of the same family, being Cross-Entropy Methods and CMAES. The comparison suggests the derivation of a novel algorithm which we call PI2-CMA for ``Path Integral Policy Improvement with Covariance Matrix Adaptation''. PI2-CMA's main advantage is that it determines the magnitude of the exploration noise automatically}, bib2html_pubtype = {Refereed Conference Paper}, bib2html_rescat = {Reinforcement Learning of Robot Skills} }
