Wearables already track heart rate, sleep timing, and sometimes even blood oxygen. But obstructive sleep apnea (OSA) isn’t just “events happened” vs. “events didn’t happen”—there are differ

Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss, and scaling reliable screening from routine retinal photos (digit

Their appearance shifts across patients, lead configurations, sensor types, and recording environments. This variability has long pr

Publication: https://iopscience.iop.org/article/10.1088/1361-6579/ae2231/meta Deep learning has changed the way we analyze physiological time-series such as ECG, SpO₂, and PPG signals. Modern neural networks routinely match and sometimes exceed expert performance in clinical tasks, from detecting atrial fibrillation to staging sleep. But there’s a catch: these models often break when moved from one patient popu
