Figure 3.
Three-stage classification confusion matrices, comparing staging by sleep technicians vs. network predictions on the testing set for different input signals. The three “super-stages” here are: “awake” (W) vs. “NREM sleep” (N1+N2+N3) vs. “REM sleep” (R). The top two rows are based on the pooled MGH testing set from all folds. The bottom two rows are based on the external validation SHHS dataset.
