Human-like Social Learning for Social Robots: A Systematic Review

Social learning is a learning paradigm aiming to make the process of teaching new skills to an artificial intelligent agent (such as a robot) as close as possible to the process we employ when teaching skills to other humans. Equipping robot companions with the ability to learn from social interactions with their users would enable naive users to effortlessly teach skills to robots and support personalization and long-term use. Aiming to support research on the field, in this article we present a systematic literature review of human-like social learning for social robots, with a specific focus on works employing real robots and real human-robot social interactions. The review examines relevant papers from perspectives including the type of robot used, the task to be learned, and the method and assessment metrics employed, and allows for the identification of open research avenues.
