Proceedings of the second "international Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST'14)
L. Jacques, C. De Vleeschouwer, Y. Boursier +64
The implicit objective of the biennial "international - Traveling Workshop on Interactions between Sparse models and Technology" (iTWIST) is to foster collaboration between interna…
Homotopy based algorithms for -regularized least-squares
Charles Soussen, Jérôme Idier, Junbo Duan +1
Sparse signal restoration is usually formulated as the minimization of a quadratic cost function , where A is a dictionary and x is an unknown sparse vector. It is we…
Relaxed Recovery Conditions for OMP/OLS by Exploiting both Coherence and Decay
Cédric Herzet, Angélique Drémeau, Charles Soussen
We propose extended coherence-based conditions for exact sparse support recovery using orthogonal matching pursuit (OMP) and orthogonal least squares (OLS). Unlike standard uniform…
