WebFirstly, dataset oversampling was performed by SMOTE to erase class imbalance; then, K-part Lasso was utilized to select the existing redundant features; finally, recursive feature … WebFeatures for classification were selected using a support vector machine recursive feature elimination (SVM-RFE) algorithm. The classification model was developed using LibSVM, and its performance was assessed on the testing dataset. Results: The final analysis included 15 subjects in the Managed group and 191 in the Control group.
