Other professional activities

Co-organization of the third GENEVA EMOTION WEEK (GEW '95) on Artificial Emotions. The intention of GEW'95 is to bring together researchers from diverse disciplines, including AI, neurosciences, philosophy, and psychology, who share an interest in architectures and mechanisms underlying emotion, motivation, and intelligence. The focus is on architectural requirements for an autonomous agent, combining the various sub-functions and sub-mechanisms normally studied separately in AI and Psychology.
