New agent architecture improves wrist PPG heart rate accuracy

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel agent architecture designed to improve the accuracy of wrist-based photoplethysmography (PPG) heart rate estimates. This system utilizes tools and memory to selectively correct errors caused by motion artifacts, which often degrade individual measurement windows. By analyzing pulse, motion, and historical data, the architecture predicts the benefits and harms of candidate estimates, guiding a risk gate to retain, correct, or reject outputs. Tested on four public datasets, the system demonstrated a significant reduction in mean absolute error, up to 44.5%, while also quantifying the risks and benefits of its corrections. AI

IMPACT This architecture could lead to more reliable wearable health monitoring devices by improving the accuracy of heart rate data.

    An Agent Architecture with Tools and Memory for Selective Correction of Wrist PPG Heart Rate Estimates

    arXiv:2610.30688v1 Announce Type: new Abstract: Wrist photoplethysmography (PPG) heart rate estimates are vulnerable to motion artifacts, and corrections that reduce mean error can worsen individual windows. We propose an agent architecture with tools and memory around a fixed he…
