The Idiap Speaker Series are monthly lectures by leading researchers in human and media computing and related areas. The invited speakers will visit our Institute, discuss new trends in academia and industry, and interact with our community. The talks are open to the public.
The Series is currently coordinated by Jean-Marc Odobez.
From 2013 to july 2014, it was coordinated by Daniel Gatica-Perez and Oya Aran.

How technology is opening up new potential for democracy, participation and collaboration

The barriers to production are being lowered so it's a good time to build platforms which make it as simple as possible for everyone to join in and help train and refine language technologies, share their stories and spread the word. Gareth draws on digital storytelling with the BBC, democratic activism via hyperlocal journalism and tools for citizenship to see if there's a new way to corral people's enthusiasm for languages to help build better, more relevant resources.

Probabilistic Models for Music Performance: Interaction, Creation, Cognition

Music performance is an epitome of complex and creative motor skills. It is indeed striking that musicians can continuously show more physical virtuosity in playing their instrument and can show more creativity in varying their interpretation. Technology-mediated music performance has naturally explored the potential of interfaces and interactions for enhancing musical expression. It is however a difficult (and ill-posed) problem and musical interactive systems cannot yet challenge traditional instruments in terms of expressive control and skill learning.
I believe that an important aspect of the problem relies on the understanding of variability in the performer’s movements. I will start my talk by presenting the computational approach based on probabilistic models, particularly suited to handle uncertainty in motion data that stem from noise or intentional variations of the performers. I will then illustrate the potential of the approach in the design of expressive music interactions through experiments with proofs of concept developed and evaluated in the lab; as well as real world applications in artistic projects and in industrial products for consumer devices. Finally, I will present my upcoming EU-funded research project that takes a more theoretical perspective by examining how this approach could potentially be used to infer an understanding of the cognitive processes underlying sensorimotor learning in music performance.

Baptiste Caramiaux is a Marie Sklowodska Curie Research Fellow between McGill University (Montreal, Canada) and IRCAM (Paris, France). His current research focuses on the understanding of the cognitive processes of motor learning in musical performance and the computational modelling of these processes.  Before, he worked on gesture expressivity and the design of musical interactive systems through machine learning. He conducted academic research at Goldsmiths University of London, and applied part of his academic research works on industrial products at Mogees Ltd. Baptiste holds a PhD in computer science from University Pierre et Marie Curie in Paris, and IRCAM Centre Pompidou.

Shape, Medialness and Applications


I will present on-going research in my group with a focus on shape understanding with applications to computer vision, robotics and the creative industries. I will principally discuss our recent work on building an algorithmic chain exploiting models of shape derived from the cognitive science literature but relating closely to well-known approaches in computer vision and computational geometry: that of medial descriptors of shape.

Short bio:

Frederic Fol Leymarie is a Professor of Computing at Goldsmiths, University of London since late 2004. Previously he was the co-founder of the SHAPE Lab. at Brown University (1999) and later its Lab manager (2002-4) while a postdoctoral fellow. He completed his PhD thesis at Brown in 2002 on the topic of 3D Shape Representation by Shock Scaffolds. This work was supported in part by two (US) NSF grants Frederic co-wrote and one IBM Doctoral Fellowship
(1999). Since joining Goldsmiths, Frederic has launched and directed the MSc Arts Computing (2004-7), as well as the MSc Computer Games Entertainment (since 2008) and the MA Computer Games Art and Design (starting in Sept. 2015), both of these in collaboration with Prof. William Latham.
