Figure 7. Radiomics features extraction and prediction model establishment in the training set. (A) The 5 features were finally identified by mRMR and RFE algorithms. (B) The prediction performance of the model established by SVM method. (C) Variables importance assessment in SVM model. (D) The prediction performance of the model established by LR method. (E) Variables importance assessment in SVM model. Abbreviation: SVM, Support Vector Machine; LR, Logistic regression.
