초록

Obstructive sleep apnea (OSA) is a common sleep disorder, causing disrupted sleep and reduced oxygen levels in the blood. Full-night polysomnography (PSG) and home sleep apnea tests (HSAT) may offer acceptable diagnosis results but have shown some limitations. In recent years, deep learning and data analysis methods are progressively employed on electronic health records, and various methods have been developed for OSA event detection. Self-supervised learning has shown some advantages over supervised training methods, by learning more generalized feature representation of data. Unlike text or image processing, the high information density in multivariate time-series data makes it more challenging to utilize self-supervised learning. In this research, based on the characteristics of sleep dataset, we propose a self-supervised approach with Masked Autoencoder, which masks portions of the input and attempting to reconstruct them. This enables the model to learn more generalized features from unlabeled data. We evaluate our proposed framework with three independent sleep datasets, which have shown significant improvement compared to supervised learning models.
