Developmental Modular Reinforcement Learning

Overview & Synopsis

In this article, we propose a modular reinforcement learning (MRL) architecture that coordinates the competition and the cooperation between modules, and inspire, in a developmental approach, the generation of new modules in cases where new goals have been detected. We evaluate the effectiveness of our approach in a multiple-goal torus grid world. Results show that our approach has better performance than previous MRL methods in learning separate strategies for sub-goals, and reusing them for solving task-specific or unseen multi-goal problems, as well as maintaining the independence of the learning in each module.
