Figure 7. The diagnosis model and ROC analysis of the model based on LASSO and SVM. (A) The relationship curve between l1 norm and coefficient in the Lasso regression of DEICDRGs. (B) The cross-validation result of Lasso regression. (C) The result of using SVM regression to filter features. (D) The Wayne diagram of the intersection of characteristic genes screened by Lasso and SVM. (E, F) are ROC analysis of the diagnosis model in the training set and test set, respectively.
