FIGURE 1 LASSO algorithm on feature selection. Fig. 1A, 1C and 1E show Lasso path of CMP, NP and CMP+NP, respectively; Fig. 1B, 1D and 1F demonstrate coefficients in Lasso model of CMP, NP and CMP+NP, respectively. Using Lasso model, 6, 5 and 6 optimal features, corresponding to the optimal alpha value of CMP, NP and CMP+NP respectively, were identified.
