| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary The proposed three-stage approach for sleep stage classification using ECG signals offers a more accessible alternative to traditional methods that often rely on complex modalities like EEG. The approach initializes the weights of two networks, which are then integrated in Stage 3 for comprehensive classification. Key features are estimated using Feature Imitating Networks (FINs) to achieve higher accuracy and faster convergence. The model identifies N1 sleep stage through time-frequency representation of ECG signals and employs a Kolmogorov-Arnold Network (KAN) to classify five distinct sleep stages. Data augmentation techniques, particularly SMOTE, are used to enhance classification capabilities for underrepresented stages like N1. The results demonstrate significant improvements in the classification performance, with an overall accuracy of 80.79% and an overall kappa of 0.73. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary Sleep stage classification is important for understanding sleep disorders and improving health. A new approach uses ECG signals to classify five distinct sleep stages: Wake, N1, N2, N3, and REM. The approach has three stages: estimating key features using Feature Imitating Networks (FINs), identifying the N1 sleep stage through time-frequency representation of ECG signals, and integrating models to classify all stages. Data augmentation helps improve classification for underrepresented stages like N1. This approach can help diagnose sleep disorders more accurately. |
