Cross-Sensor Transferability of a Deep Residual U-Net for Sleep Staging Using Temporal Low-Frequency Photoplethysmography

Abstract: Wearable sensors are increasingly used for sleep monitoring, but accurate sleep staging often depends on expensive, high-fidelity devices and hand-crafted features. This work explores ...
