arXiv:2606.07365v1 Announce Type: new Abstract: Photoplethysmography (PPG), a non-invasive measure of changes in blood volume, is widely used in both wearable devices and clinical settings. Recent PPG foundation models either use open-source ICU datasets with pretraining paradigms that require curated data and thus complicate generalization to field-like data, or use closed-source field-like PPG data. In contrast, we propose a PPG foundation model that does not require high-quality or field-like pretraining data, and instead leverages accompanying electrocardiogram and respiratory signals in I
The development of robust physiological foundation models is critical as AI integrates further into health tech and wearable devices, necessitating models that generalize effectively to real-world, often imperfect, data.
This breakthrough advances the capability of AI models to interpret physiological data reliably without extensive, high-quality pretraining, which democratizes access and accelerates innovation in health monitoring.
The reliance on curated or closed-source datasets for developing PPG foundation models is reduced, enabling more adaptable and robust AI for health applications across various settings.
