Researchers have developed NanoSleep, a compact hybrid temporal convolutional network designed for efficient sleep stage classification from single-channel EEG data. This model integrates several novel components, including a learnable Sinc-convolutional front end, a dual-branch feature extractor, and a gated dilated temporal convolutional backbone with channel recalibration. It also utilizes a conditional random field for sequence-level decoding and a weighted calibrated focal loss to handle class imbalance. Evaluated on the Sleep-EDF and Sleep-EDF-Expanded datasets, NanoSleep demonstrated superior performance compared to six baseline methods, highlighting its effectiveness for resource-constrained applications like wearable sleep monitoring.
