Fig. 2From: Sparse Proteomics Analysis – a compressed sensing-based approach for feature selection and classification of high-dimensional proteomics mass spectrometry data a Overlaid spectra from two different groups. The three peaks marked by the arrows (magnified in the inlays) represent the underlying differences between the two groups. b Sparse ω found by a ℓ 1-regularized method (ℓ 1-SVM). c ω found by ℓ 2-regularized method (classical SVM)Back to article page
