Learning Co-Sparse Analysis Operators with Separable Structures
Matthias Seibert, Julian Wörmann, Rémi Gribonval +1
In the co-sparse analysis model a set of filters is applied to a signal out of the signal class of interest yielding sparse filter responses. As such, it may serve as a prior in in…

Projection onto the Cosparse Set is NP-Hard
Andreas M. Tillmann, Rémi Gribonval, Marc E. Pfetsch
The computational complexity of a problem arising in the context of sparse optimization is considered, namely, the projection onto the set of -cosparse vectors w.r.t. some given…

The restricted isometry property meets nonlinear approximation with redundant frames
Rémi Gribonval, Morten Nielsen
It is now well known that sparse or compressible vectors can be stably recovered from their low-dimensional projection, provided the projection matrix satisfies a Restricted Isomet…
