Personal tools


The test ground to explore new methods for sparse models.

In a nutshell...


Sparse representations, reproducible research.

Why a new toolbox?

  • To provide an easy way to evaluate methods against state-of-the art alternatives.
  • To provide interoperability between existing state-of-the art toolboxes: Sparco, Sparselab, Sparsify, KSVD, SKSVD, etc.

Inside the box

A unifying interface that enables a seamless connection between three types of modules:

  • problems;
  • dictionary learning algorithms;
  • sparse solvers.
