Reinforcement Learning for Robot Learning

Abstract: Robot Learning has seen explosive growth and interest in recent years and it is one of the biggest modern challenges for Artificial Intelligence. After a short introduction to general Reinforcement Learning, I will present three robotic systems we worked on and solved using Model-based Reinforcement Learning (MBRL). In particular, I will focus on the modeling techniques we developed, that combine physical and data-driven models using semiparametric Gaussian Process regression, to learn the dynamics of these physical systems. After that, I will introduce a data efficient model-free RL algorithm that we recently developed as an extension of the TRPO algorithm, called Quasi-Newton TRPO. The algorithm is validated in learning the policy of several OpenAI Gym environments. Finally, I will try to point out some future research directions that we are currently interested on.
