Machine Learning for Social Multiparty Human--Robot Interaction

Machine Learning for Social Multiparty Human--Robot Interaction Machine Learning for Social Multiparty Human­Robot Interaction SIMON KEIZER, MARY ELLEN FOSTER, ZHUORAN WANG, and OLIVER LEMON, Heriot-Watt University We describe a variety of machine-learning techniques that are being applied to social multiuser human­ robot interaction using a robot bartender in our scenario. We first present a data-driven approach to social state recognition based on supervised learning. We then describe an approach to social skills execution-- that is, action selection for generating socially appropriate robot behavior--which is based on reinforcement learning, using a data-driven simulation of multiple users to train execution policies for social skills. Next, we describe how these components for social state recognition and skills execution have been integrated into an end-to-end robot bartender system, and we discuss the results of a user evaluation. Finally, we present an alternative unsupervised learning framework that combines social state recognition and social skills execution based on hierarchical Dirichlet processes and an infinite POMDP interaction manager. The models make use of data from both human­human interactions collected in a number of German bars and human­robot interactions recorded in the evaluation of an initial version of the system.
