Can we still use existing sleep stage classification models in the label-scarce scenarios?

We aim to provide a realistic assessment of sleep stage classification (SSC) models in real-world label-scarce scenarios. Most of the proposed deep learning-based models assume access to a vast amount of labeled data, which is not usually achievable. What was the approach to solving the problem? We explored the efficacy of self-supervised learning (SSL) algorithms in scenarios with limited labeled data. Keep reading

Exploration of sleep disturbances in children and adolescents with and without autism in a paediatric sample referred for polysomnography

Sleep disturbances in children and adolescents are important to identify as they affect daytime function, and, although extremely common, can be especially hard to diagnose in those with autism. For this reason, the description of the type and frequency of sleep diagnoses in the pediatric autism population has been elusive to researchers, clinicians, and caregivers. Keep reading

Automatic sleep staging for the young and the old – Evaluating age bias in deep learning

AI for automated sleep staging is considered mature and has found its way to commercial sleep evaluation systems. Systems underpinned by deep learning require large datasets providing a broad sample of sleep stages the machine seeks to ‘learn’. Of concern, most databases used for developing AI sleep stagers include only recordings from adults, creating a significant inherent sample bias when applied to when applied in the pediatric or geriatric sleep setting.

Harmonizing sleep and circadian data: why is it important?

Guest Blogger: Diego R. Mazzotti, Ph.D. University of Kansas Medical Center In this post, we will discuss some of the highlights of a Workshop Report recently published in SLEEP1 by our colleagues at the Sleep Research Network (SRN), a Task Force from the Sleep Research Society (SRS). This report summarizes a discussion panel held at the World Sleep Congress in Vancouver, Canada in 2019, that brought together leaders in sleep, circadian sciences, and biomedical informatics.

Characterizing Mortality and CVD for Co-Morbid Insomnia and Sleep Apnea (COMISA) in the Sleep Heart Health Study

What is the problem being addressed? Insomnia and obstructive sleep apnea commonly co-occur (COMISA). Their co-occurrence has been associated with worse cardiometabolic and mental health. However, it remains unknown if people with COMISA are at a heightened risk of incident cardiovascular events and all-cause mortality. Keep reading
