Receiver Operating Characteristic (ROC) curves of three baseline models on the test set. ROC curves comparing the performance of (A) Soft MoE-ViT, (B) Standard ViT, and (C) ResNet50 for binary classification of frozen-section WSIs. Soft MoE-ViT achieved the highest AUC (0.957), followed by Standard ViT (0.934) and ResNet50 (0.921). The optimal operating points selected from the validation set are indicated on each curve.
