To investigate the approach of classification and prediction methods using the machine learning (ML)-based optimized combination-feature (OCF) set on gray matter volume (GMV) and QSM in elderly subjects with a cognitive normal (CN) profile, those with amnestic MCI (aMCI), and mild and moderate AD patients, GMV and QSM in the brain were calculated. To differentiate the three subject groups, the support vector machine (SVM) with the three different kernels and with the OCF set was conducted with GMV and QSM values. To predict the aMCI stage, regression-based ML models were developed with the OCF set.
