Policy transfer in mobile robots using neuro-evolutionary navigation

Published: 07 July 2012 Publication History

Abstract

In this paper, we first present a state/action representation that allows robots to learn good navigation policies, but also allows them to transfer the policy to new and more complex situations. In particular, we show how the evolved policies can transfer to situations with: (i) new tasks (different obstacle and target configurations and densities); and (ii) new sets of sensors (different resolution). Our results show that in all cases, policies evolved in simple environments and transferred to more complex situations outperform policies directly evolved in the complex situation both in terms of overall performance (up to 30%) and convergence speed (up to 90%).
