The classification results of each class using the untargeted method represented by a confusion matrix. (a) DFDL with the untargeted method. (b) SVM_rbf with the untargeted method. The diagonal elements represent the classification accuracy for which the predicted class is equal to the actual class, while the off-diagonal elements indicate those that are misclassified. Sensitivities and specificities for each class are calculated.
