Fig. 3From: Improved iterative shrinkage-thresholding for sparse signal recovery via Laplace mixtures modelsExperiment 2: comparison of compressibility parameters (κ,ε) for several priors. Laplace distribution is not a compressible distribution, whereas for 2-LMM distribution if parameter p is small and α< <β we can have both κ and ε small at the same time. In this case α=0.1, β=10, and p∈[0.02,0.1]Back to article page
