An Interactive Learning and Adaptation Framework for Adaptive Robot Assisted Therapy

摘要

In this paper, we present an interactive learning and adaptation framework. The framework combines Interactive Reinforcement Learning methods to effectively adapt and refine a learned policy to cope with new users. We argue that implicit feedback provided by the primary user and guidance from a secondary user can be integrated to the adaptation mechanism, resulting at a tailored and safe interaction. We illustrate this framework with a use case in Robot Assisted Therapy, presenting a Robot Yoga Trainer that monitors a yoga training session, adjusting the session parameters based on human motion activity recognition and evaluation through depth data, to assist the user complete the session, following a Reinforcement Learning approach.
