Figure 3. Regression and Classification Results on the Training-Testing Set.

Figure 3.

(a) Correlation analysis between VO2 predicted vs VO2 actual for the training and testing set. (b) The blue curve is showing the receiver operating characteristic (ROC) curve for the SVM classifier with RBF kernel for the training and testing set. The red line is the ROC curve for classification based on random chance. The area under the blue ROC curve (AUC) is 0.74.
