Contactless sleep stage classification

MSc thesis: dual-stream LSTM for contactless physiological sleep staging.

MSc research, 2025

Designed and trained a dual-stream LSTM to classify sleep stages from contactless physiological sensors, fusing multiple sensor modalities without requiring wearables or skin contact. Completed with the Surrey Sleep Research Centre.

• Multimodal sensor fusion across contactless physiological signal streams
• Dual-stream LSTM architecture tuned for temporal sleep-stage transitions
• 78% F1 on held-out evaluation, validated against clinical staging conventions
