Fig. 2From: Predicting conversion of brain β-amyloid positivity in amyloid-negative individualsReceiver operating characteristic curves of three artificial neural network models that classify the β-amyloid positivity within 5 years. Mean curves of 10 times repeated 10-fold cross-validation are plotted. Each model included the following features for training with the Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset: Model 1: age + gender + APOE ε4 carriers, Model 2: features from Model 1 + global SUVR, and Model 3: features from Model 2 + regional SUVRBack to article page
