Optimizing automated sleep stage scoring of 5-second mini-epochs: a transfer learning study

Louise Frøstrup Follin, Julie Anja Engelhard Christensen, Janita Vevelstad…·Stine Knudsen

This paper optimizes an existing deep learning model for 5-second sleep stage scoring, achieving performance comparable to human and 30-second automated scoring, and demonstrating increased capture of sleep transitions.
