Researchers have developed a new framework called SPAFT to improve the specialization of foundation models for photoplethysmogram (PPG) signals used in wearable health monitoring. Existing models often struggle to adapt to real-world, low-quality data despite fine-tuning. SPAFT addresses this by identifying and pruning computational redundancy within these models, regularizing the fine-tuning process to focus on task-relevant network substructures. Experiments show that SPAFT significantly enhances the performance of PPG foundation models across various datasets and tasks, achieving high win rates for both regression and classification. AI
