MMP14 is a diagnostic gene of intrahepatic cholangiocarcinoma associated with immune cell infiltration

Figure 4 Screening of disease signature genes. A: The process of least absolute shrinkage and selection operator regression screening of characteristic genes; B: The relationship between the error and the number of variables in support vector machine-recursive feature elimination; C: The impact of the amount of decision trees on the error rate; D: The name of the characteristic gene and the score of gene importance obtained by RF screening; E: The Venn diagrams of the intersection eigengenes obtained by the three algorithms. SVM: Support vector machine; LASSO: The least absolute shrinkage and selection operator; RF: Random forest.
