Why the study?
Sleep stage detection algorithms can significantly reduce manual sleep staging workload and improve sleep disorder diagnostics, motivating the evaluation of automated scoring using a single frontal EEG channel.
Does automatic sleep stage detection using a single channel frontal EEG perform as effectively as using central and occipital EEGs?
Does automatic sleep stage detection using a single channel frontal EEG perform as effectively as using central and occipital EEGs?
A single frontal channel EEG combined with a random forest classifier can automatically detect sleep stages with reasonable accuracy, potentially reducing the workload of manual sleep staging.
Single frontal EEG with ML supports simplified staging research; leaves open head-to-head validation against standard montages.
Sleep stage detection algorithms can significantly reduce the workload of manual sleep staging and in improving sleep disorder diagnostics. In this paper, we focus on the automatic detection of sleep stages from a frontal channel EEG using expert defined features in both time and frequency domain, fed to a random forest classifier. The proposed approach shows that using a single frontal channel EEG signal as input to automated sleep scoring algorithms is as effective as using EEGs recorded from the central and occipital regions. Mean overall accuracy, precision and recall were respectively of 72.98%, 79.75% and 71.83%, when validating our method on the MGH (Massachusetts General Hospital), You snooze, you win dataset.
