Performance metrics of the RF classifier for all five algorithms for the ADNI dataset: A bar chart that shows (a) the mean accuracy, (b) sensitivity, (c) specificity and (d) ROC-AUC scores for each algorithm calculated from the tenfold cross-validation for the SVM classifier. The best and most consistent results were acquired with the LCOR metric (82%). SVM support vector machine, ICC intrinsic connectivity, LCOR local correlation, fALFF fractional amplitude of low frequency fluctuations, SFFS sequential floating forward selection, NSGA-II non-dominated sorting genetic algorithm concatenated metrics: the three metrics combined resulting in 396 (3 × 132) regions.
