Homotopy based algorithms for $ℓ_{0}$ -regularized least-squares

Charles Soussen, Jérôme Idier, Junbo Duan +1

Sparse signal restoration is usually formulated as the minimization of a quadratic cost function $∥ y - A x ∥_{2}^{2}$ , where A is a dictionary and x is an unknown sparse vector. It is we…

A sufficient condition on monotonic increase of the number of nonzero entry in the optimizer of L1 norm penalized least-square problem

J. Duan, Charles Soussen, David Brie +2

The $ℓ$ -1 norm based optimization is widely used in signal processing, especially in recent compressed sensing theory. This paper studies the solution path of the $ℓ$ -1 norm…
