Dr. Sylvain Calinon

Head of the Robot Learning & Interaction Group


Visit personal webpage


Dr. Sylvain Calinon has been a permanent researcher at Idiap since May 2014, with research interests covering robot learning and human-robot interaction.

His research focuses on human-centric robotic applications in which the robots can learn new skills by interacting with the end-users. The challenge is to acquire skills from only few demonstrations and interactions, with strong generalization requirements. This requires the development of intuitive active learning interfaces to acquire meaningful demonstrations, the development of models that can exploit the structure and geometry of the acquired data in an efficient way, and the development of adaptive control techniques that can exploit the learned task's variations and coordination patterns.
