Figure 8.

MESA dataset (n = 188) validation of neural net models trained on the Apple Watch-PSG dataset. Left) Sleep/wake differentiation performance in MESA dataset Right) Wake/NREM/REM classifier performance in MESA dataset. The dashed lines represent REM accuracy for the motion-only feature set; the dotted lines represent NREM accuracy for the motion-only feature set. For all, solid lines represent the average of the NREM and REM accuracies, chosen to be as close to equal as possible via threshold selection. NREM, non-rapid eye movement; REM, rapid eye movement.
