Beyond Motion Artifacts: Optimizing PPG Preprocessing for Accurate Pulse Rate Variability Estimation

Yuna Watanabe, Natasha Yamane, Aarti Sathyanarayana +2

Wearable physiological monitors are ubiquitous, and photoplethysmography (PPG) is the standard low-cost sensor for measuring cardiac activity. Metrics such as inter-beat interval (…

Topological Data Analysis of Electroencephalogram Signals for Pediatric Obstructive Sleep Apnea

Shashank Manjunath, Jose A. Perea, Aarti Sathyanarayana

Topological data analysis (TDA) is an emerging technique for biological signal processing. TDA leverages the invariant topological features of signals in a metric space for robust…
