Screening of diagnostic biomarkers for DCM by machine learning algorithms. (a) Screening of optimal genes by LASSO regression model. (b) Plot of the best gene selected by SVM-RFE algorithm. (c) Venn diagram embodying the eight diagnostic biomarkers common to both machine learning algorithms. LASSO, least absolute shrinkage and selection operator; SVM-RFE, support vector machine-recursive feature elimination.
