Graph based skill acquisition and transfer Learning for continuous reinforcement learning domains

Introducing connectivity graph to model agent behavior and environment dynamics.A graph based approach for automatic skill acquisition.A skill based transfer learning method in continuous reinforcement learning domain. Since reinforcement learning algorithms suffer from the curse of dimensionality in continuous domains, generalization is the most challenging issue in this area. Both skill acquisition and transfer learning are successful techniques to overcome such problem that result in big improvements in agent learning performance. In this paper, we propose a novel graph based skill acquisition method, named GSL, and a skill based transfer learning framework, named STL. GSL discovers skills as high-level knowledge using community detection from connectivity graph, a model to capture not only the agents experience but also the environments dynamics. STL incorporates skills previously learned from source task to speed up learning on a new target task. The experimental results indicate the effectiveness of the proposed methods in dealing with continuous reinforcement learning problems. Display Omitted
