New P2E-VQ framework augments PPG data with ECG-linked representations

Researchers have developed P2E-VQ, a novel framework that enhances photoplethysmogram (PPG) data by linking it with electrocardiography (ECG) information. Instead of attempting to reconstruct ECG signals from PPG, P2E-VQ converts PPG segments into discrete tokens and retrieves relevant ECG-linked representations from a memory bank. This method augments PPG data without requiring ECG signals during inference and has demonstrated superior performance across various downstream tasks, including clinical endpoint prediction and affective state recognition, compared to existing pretrained models.
