  1. AUC sensitivity, specificity, PPV and NPV metrics have different values per class following the one-vs-rest scheme. Performance improvement is observed for the architecture that includes attention mechanism. Auto-Prognose-CNNattention (SegforClass) framework consists of the tumor segmentation model followed by the prognostic prediction model.
