UW roboticists learn to teach robots from babies

Researchers at the University of Washington have created a new probabilistic model that allows robots to learn new skills by watching people and imitating them. The team combined child development research with machine learning approaches, inspired by infants' ability to infer adult intentions through self-exploration.
