From Humans and Back: a Survey on Using Machine Learning to both Socially Perceive Humans and Explain to Them Robot Behaviours

Abstract

As intelligent robots enter our daily routine, it is important to be equipped with proper adaptable social perception and explainable behaviours. To do so, machine learning (ML) is often employed. This paper intends to find a trend in the way ML methods are used and applied to model human social perception and produce explainable robot behaviours. The literature has shown a substantial advancement in ML methods with application to social perception and explainable behaviours. There are papers which report models for robots to imitate humans and also for humans to imitate robots. Others use classical methods and propose new and/or improved ones which led to better human-robot interaction performances. This paper reports a review on social perception and explainable behaviours based on ML methods. First, we present literature background on these three research areas and finish with a discussion on limitations and future research venues.
