Practical error estimates for sparse recovery in linear inverse problems

Ignace Loris, Caroline Verhoeven

The effectiveness of using model sparsity as a priori information when solving linear inverse problems is studied. We investigate the reconstruction quality of such a method in the…

Accelerating gradient projection methods for $ℓ_{1}$ -constrained signal recovery by steplength selection rules

I. Loris, M. Bertero, C. De Mol +2

We propose a new gradient projection algorithm that compares favorably with the fastest algorithms available to date for $ℓ_{1}$ -constrained sparse recovery from noisy data, both…
