Continuous unsupervised sleep staging based on a single EEG signal

Arthur Flexer, Georg Gruber, Georg Dorffner

We report improvements on automatic continuous sleep staging using Hidden Markov Models (HMM). Our totally unsupervised approach detects the cornerstones of human sleep (wakefulness, deep and rem sleep) with around 80% accuracy based on data from a single EEG channel. Contrary to our previous efforts we trained the HMM on data from a single sleep lab instead of generalizing to data from diverse sleep labs. This solved our previous problem of detecting rem sleep.
