Fig. 11
An illustration of three line graphs labeled a, b, and c showing EXPECTED l one RISK versus alpha, comparing ACTUAL RISK and ESTIMATED RISK.

(Color online) The expected ℓ1-risk and its estimate versus a, averaged over 100 noise realizations for: (a) Gaussian noise with σ2 = 1; (b) three-component GMM; and (c) a four-component GMM approximation to the Laplacian distribution.
