Heat map summary for classification performance of different machine-learning algorithms using DTI and connectome metrics for identification of children with ASD. The accuracy, sensitivity, specificity, PPV, and NPV were calculated in validation datasets from × 1,000 cross-validation—details provided in Table 3. In each column, yellow to red color range is assigned to values from low to high, respectively. DTI, diffusion tensor imaging; SVM, support vector machine; PPV, positive predictive value; NPV, negative predictive value. Color images are available online.
