One of most successful Polish startup companies, Neuroon, made a claim they can automatically classify sleep stages and increase sleep quality using a small wearable mask.
We compared the sleep stage classification produced by Neuroon with a clinical standard polysomnography recording.
We have divided the Neuroon validation into three stages:
- First we assessed whether the EEG signal collected with Neuroon is similar at any point in time to the polysomnography EEG signal.
- Second we assessed accuracy with which Neuroon predicted the sleep stage.
- Third we assessed whether there is enough information in the EEG signal to discriminate on that basis between the sleep stages.
