Improved iterative shrinkage-thresholding for sparse signal recovery via Laplace mixtures models
In this paper, we propose a new method for support detection and estimation of sparse and approximately sparse signals from compressed measurements. Using a double Laplace mixture model as the parametric representation of the signal coefficients, the problem is formulated as a weighted ℓ(1) minimiza...
