Abstract
Basis Pursuit (BP) and Basis Pursuit Denoising (BPDN),
well established techniques for computing sparse
representations, minimize an
ℓ2 data fidelity term,
subject to an ℓ1
sparsity constraint or regularization term, by mapping the
problem to a linear or quadratic program. BPDN with an
ℓ1 data fidelity term
has recently been proposed, also implemented via a mapping to a
linear program. We introduce an alternative approach via an
Iteratively Reweighted Least Squares algorithm, providing
computational advantages and greater flexibility in the choice
of data fidelity term norm.
