Fig. 4From: InsightSleepNet: the interpretable and uncertainty-aware deep learning network for sleep staging using continuous PhotoplethysmographyProportion of samples rejected based on four different energy score thresholds for each dataset. The rejection rate is calculated with respect to the state before energy-based rejection. The blue confusion matrix represents the MESA dataset, the green one corresponds to the CFS dataset, and the purple one represents the CAP dataset. LS means 'Light sleep' and DS means 'Deep sleep'. W means 'Wake'Back to article page
