Sleep Sound Event Detection Powered by Learnable Multi-Resolution Adaptive Line Enhancer

Sleep-disordered breathing, including snoring, hypopnea, and obstructive apnea, is the hallmark of obstructive sleep apnea, whose severity is quantified by the Apnea-Hypopnea Index (AHI). As conventional polysomnography is costly and clin- ically demanding, microphone-only detection has emerged as a noninvasive alterna...

Delta2Gamma: Band-Wise Adaptive Contrastive Learning of EEG for Alzheimer's Disease Detection

Delta2Gamma, a self-supervised framework that learns EEG representations from unlabeled data by contrasting augmented views of each signal by decomposing every recording into the five canonical neural rhythms, separates Alzheimer's disease from cognitively normal controls with 92.4\% accuracy.
