Title
Iteratively Reweighted $\ell_1$ Approaches to Sparse Composite Regularization.
Abstract
Motivated by the observation that a given signal x admits sparse representations in multiple dictionaries Ψd but with varying levels of sparsity across dictionaries, we propose two new algorithms for the reconstruction of (approximately) sparse signals from noisy linear measurements. Our first algorithm, Co-L1, extends the well-known lasso algorithm from the L1 regularizer ∥Ψx∥1 to composite regul...
