Introduction

This Patients database was collected during the DREAMS project, to tune, train and test our automatic sleep stages classification algorithms.

It consist of 27 whole-night PSG recordings coming from patients with various pathologies, annoted in sleep stages according to both the Rechtschaffen and Kales (R&K) criteria and the new standard of the American Academy of Sleep Medicine (AASM).

In order to facilitate future research and performance comparision, we decided to publish these data on Internet. Be simply aware that this DREAMS Patients Database of University of MONS - TCTS Laboratory (Stéphanie Devuyst, Thierry Dutoit) and Université Libre de Bruxelles - CHU de Charleroi Sleep Laboratory (Myriam Kerkhofs) is under terms of the Attribution-NonCommercial-NoDerivs 3.0 Unported (CC BY-NC-ND 3.0) License.

Database description

Data collected were acquired in a sleep laboratory of a belgium hospital using a digital 32-channel polygraph (BrainnetTM System of MEDATEC, Brussels, Belgium). They consist of 27 whole-night polysomnographic recordings, coming from patients with various pathologies (diseases suffered by these patients are given in Table bellow).

At least two EOG channels (P8-A1, P18-A1), three EEG channels (CZ-A1 or C3-A1, FP1-A1 and O1-A1) and one submental EMG channel were recorded. The standard European Data Format (EDF) was used for storing. The sampling frequency was 200Hz. Corresponding physiological signals can be particularly contaminated by artifacts (notably due to the numerous movements of the sleeper during the night).

The sleep stage classification according to the Rechtschaffen and Kales (R&K) criteria has been made ​​on the basis of epochs 20 seconds, while the scoring according to the American Academy of Sleep Medicine (AASM) criteria has been completed (nearly two years later) based on epochs of 30 seconds. Both annotations were produced visually by a single expert of the sleep laboratory.
