MSED: a multi-modal sleep event detection model for clinical sleep analysis

no code implementations7 Jan 2021 Alexander Neergaard Olesen, Poul Jennum, Emmanuel Mignot, Helge B. D. Sorensen

F1 scores for the optimized joint detection model were 0. 70, 0. 63, and 0. 62 for arousals, leg movements, and sleep disordered breathing, respectively, compared to 0. 65, 0. 61, and 0. 60 for the optimized single-event models.

Automatic sleep stage classification with deep residual networks in a mixed-cohort setting

1 code implementation21 Aug 2020 Alexander Neergaard Olesen, Poul Jennum, Emmanuel Mignot, Helge B. D. Sorensen

We applied four different scenarios: 1) impact of varying time-scales in the model; 2) performance of a single cohort on other cohorts of smaller, greater or equal size relative to the performance of other cohorts on a single cohort; 3) varying the fraction of mixed-cohort training data compared to using single-origin data; and 4) comparing models trained on combinations of data from 2, 3, and 4 cohorts.

Deep transfer learning for improving single-EEG arousal detection

no code implementations10 Apr 2020 Alexander Neergaard Olesen, Poul Jennum, Emmanuel Mignot, Helge B. D. Sorensen

Datasets in sleep science present challenges for machine learning algorithms due to differences in recording setups across clinics.

Towards a Flexible Deep Learning Method for Automatic Detection of Clinically Relevant Multi-Modal Events in the Polysomnogram

no code implementations16 May 2019 Alexander Neergaard Olesen, Stanislas Chambon, Valentin Thorey, Poul Jennum, Emmanuel Mignot, Helge B. D. Sorensen

Much attention has been given to automatic sleep staging algorithms in past years, but the detection of discrete events in sleep studies is also crucial for precise characterization of sleep patterns and possible diagnosis of sleep disorders.

Automatic Detection of Cortical Arousals in Sleep and their Contribution to Daytime Sleepiness

no code implementations15 Mar 2019 Andreas Brink-Kjaer, Alexander Neergaard Olesen, Paul E. Peppard, Katie L. Stone, Poul Jennum, Emmanuel Mignot, Helge B. D. Sorensen

In a dataset of 1, 026 PSGs, the MAD achieved a F1 score of 0. 76 for arousal detection, while wakefulness was predicted with an accuracy of 0. 95.
