Fig. 5From: Learning domain-heterogeneous speaker recognition systems with personalized continual federated learningReceiver operating characteristic (ROC) curves and area under the curve (AUC) values for multi-class speaker identification using Models A (centralized training) and B (PFL Type-A). The plot shows individual ROC curves for each of the 12 groups, with different shades of blue for Model A and different shades of orange for Model B. The mean ROC curves for Model A and Model B are highlighted with thicker dashed lines. The AUC values for each curve are included in the legendBack to article page
