(B) Determination of the optimal penalty coefficient (lambda) and the minimum absolute shrinkage criterion in the Lasso regression. (C) Error rate of genes identified by SVM-RFE machine learning. (D) Accuracy rate of genes identified by SVM-RFE machine learning. (E) The top 50 genes with the highest accuracy by SVM-RFE. (F) Venn diagrams to identify the characteristic genes based on LASSO and SVM-RFE screening.
