Receiver operating characteristics (ROC) curves of SVM classifier for the training and test sets of SDBS group. The orange, green, and blue lines show the ROC curves for t-SNE, Sammon’s mapping, and PCA DR methods, respectively. AUC is the area under the curve. (a) Mean ROC curves for data from the training set and its 95% confidence bounds computed by means of Bootstrap, with 1000 replicas. (b) Mean ROC curves for data from the test set.
