SleepEns accurately detects 4 sleep–wake states. Comparison of accuracies between human experts and SleepEns (see Table 3). (a) Absolute accuracy in relation to Expert 0. (b) Acceptable accuracy as determined by Expert 0. (c) Execution time comparison between human experts and SleepEns. Note that SleepEns identify sleep-wake state in a 3-hr recording in ~6s. (d) and (e) Confusion matrices between SleepEns and Expert 0 for absolute accuracy (d) and acceptable accuracy (e). (f) Absolute accuracy comparison for each state. (g) Acceptable accuracy comparison for each state. AW: Active Wake, QW: Quiet Wake, NR: NREM Sleep, R: REM sleep, GBC: Gradient Boosting Classifier, TSEns: Time Series Ensemble. *p < .05, **p < .01 and ***p < .001 indicates significant differences.
