Researchers have developed a new hybrid framework for estimating blood pressure using photoplethysmography (PPG) signals. This approach combines a convolutional neural network (CNN) with a morphology-prior branch to capture both waveform dynamics and individual vascular characteristics. The method aims to improve personalization and reduce reliance on large datasets, achieving improved accuracy on the MIMIC-III database with mean absolute errors of 3.77 mmHg for systolic BP and 2.36 mmHg for diastolic BP. Explainability analysis using SHAP confirmed that the morphological features align with individual vascular traits, enhancing interpretability. AI
