Software

The LiMapS algorithm
A new regularization method for sparse recovery based on a fixed-point iteration schema which combines Lipschitzian-type mappings and orthogonal projectors
LiMaps package for MATLAB
The k-LiMapS algorithm
A new algorithm to solve the sparse approximation problem over redundant dictionaries based on LiMapS, but retaining the best k basis (or dictionary) atoms
k-LiMaps package for MATLAB
The PrunICA algorithm
PrunICA is way to speed-up the FastICA-like algorithms by a controlled random pruning of the input mixtures, both on the entire mixture or on fixed-size blocks when segmented
PrunICA package for MATLAB
