National initiatives

MathSTIC national initiative on sparse and structured approximations in audio signal processing

Participants : Rémi Gribonval, Sylvain Lesage, Frédéric Bimbot.

The MathSTIC initiative (projet MathSTIC) "Sparse and structured approximations in audio signal processing" (Approximations parcimonieuses structurées pour le traitement de signaux audio) funded by CNRS is a collaboration between the METISS project-team at IRISA, the Signal Processing Group at LATP, Université de Provence, Marseille, and the Musical Acoustics Lab (LAM), Université Pierre et Marie Curie, Paris. The initiative started in June 2004 and will finish in December 2005. Its goal is to "solve the main theoretical issues about the identifiability of sparse structured models for the approximation of signals with overcomplete dictionaries". In December 2004, a three-day work group SPARS'04 will be held in CIRM, Marseille. It will gather members of the initiative as well as some external partners from the French GDR ISIS and European network HASSIP. In the course of 2005, student exchange between the groups is programmed, and to conclude the initiative, a larger scale international workshop (SPARS'05) took place at IRISA, in Rennes.
