Table III.

The area Az under the ROC curve and the number of selected features for different values of stepwise feature selection parameters used in the design of the two-view classifier. The area Az was obtained from the left-out validation samples in a leave-one-case-out resampling within the training data set. The number of selected features represents the average number of selected features in each cycle of the leave-one-out process.
