Fig. 2: Analysis of confidence scores in SleepXViT.
From: Explainable vision transformer for automatic visual sleep staging on multimodal PSG signals

This analysis focuses on evaluating the confidence scores generated by the Intra-epoch ViT and Inter-epoch ViTon the KISS test set. a Reliability diagram illustrating the gap, which represents the difference between average confidence and accuracy within specific confidence intervals. b Distribution of confidence scores for the predictions. c Distribution of confidence scores from Intra-epoch ViT and Inter-epoch ViT, categorized by each sleep stage. d Class-wise confusion matrix with normalization. e Distribution of confidence scores for cases where the results predicted by the Intra-epoch ViT are modified by the Inter-epoch ViT.
