The new category SoccerJuggling is mainly initialized with three known categories FieldHockeyPenalty, Backetball and FrisbeeCatch according to the distances between them. As visualized in the figure, SoccerJuggling might share the similar scenes with FieldHockeyPenalty, and the motions of human while playing basketball, frisbee catching and soccer juggling share many same motion trajectories and motion units like running and jumping. The new category learns from the knowns by initializing the weights with the trained weights of the knowns, which enables the new categories to be trained with few samples.
