Researchers are developing advanced methods for automated sleep staging, moving beyond traditional 30-second epoch analysis. One approach utilizes Hidden Semi-Markov Models to convert coarse epoch labels into second-level annotations, improving accuracy by leveraging subtle signal shifts near sleep stage boundaries. Another method, SWINSleepNet, employs a hierarchical, context-aware framework using both time-domain EEG signals and time-frequency transformations with a Swin Transformer to capture fine temporal details and long-range dependencies, showing improved performance on challenging sleep stages and transitions.
