Figure 4: The Area Under Curve (AUC) plot as evaluated by Receiver Operating Characteristic (ROC) of various supervised models (i.e., kNN, random forest, neural network, naïve bayes, logistic regression) evaluated using target variables of (a) one-dimensional (T1-relaxation), (b) one-dimensional (T2-relaxation), (c) two-dimensional (T1-relaxation, T2-relaxation), and (d) three-dimensional (T1-relaxation, T2-relaxation, A-ratio) using leave-one-out training method. Other details can be found in Table 1.
