SUMMARY: (...): F.-X. Dupé (LIF): Generalizing CoSaMP and family
DESCRIPTION:: Generalizing CoSaMP and family\n\nTools like CoSaMP (Compress
 ed Sampling Matching Pursuit)\\\, SP (Subspace Pursuit)\\\, IHT (Iterative
  Hard Thresholding)... are now commonly used for solving linear problems w
 ith a sparse prior. In order to analyze the behavior of all these algorith
 ms many tools have been proposed and the RIP (restricted isometry property
 ) is one of most famous. In the talk we propose to generalize this family 
 of sparse algorithm to non-linear problem. Such task will ask for a new cr
 iterion for analysis and allow us to better understand to which elements t
 hese methods converge. Finally\\\, we will raise some open question and pr
 opose some future axes.
