The effect of feature number and modality on predictive performance. For each of a set of incrementally complicated models, the distribution of the area under the receiver operating curve (AUROC) values obtained from cross-validation is presented as a violin and box plot, and the single AUROC on the held-out test set is plotted as a red circle. Note the marked increase in performance associated with the addition of information, especially from cranial imaging
