Selection procedure of diagnostic markers for EMT diagnoses. (A, B) Tuning feature selection in the LASSO model. (C, D) Biomarker signature gene expression validation through the SVM-RFE arithmetic. (E) RandomForest error rate versus the number of classification trees. F The top 10 relatively important genes. (G, H) Venn graph presenting 3 diagnostic biomarkers shared by the LASSO, SVM-RFE and RandomForest arithmetic methods.
