Cover Story: Socially-assistive robotics has been extensively used for a variety of applications, including educational assistants, exercise coaches and training task instructors. It is essential that such systems monitor task engagement to personalize their training strategies and maximize the effects of the training session. In this article, we present an interactive reinforcement learning approach to combine task engagement and performance and facilitate personalization in a cognitive training session.
