Koji Inoue and colleagues at Japan's Kyoto University have developed an artificial intelligence system that can guide a robot to laugh in the right way at the appropriate time.

The team annotated the conversational data for solo laughs, social laughs, and mirth-related laughter, then trained a machine learning system to decide whether to laugh, and to select the appropriate laughter type. Researchers tested Erica's sense of humor by creating dialogues for it to share with a person and integrating the shared-laughter algorithm into its conversation software.
