This paper introduces the Individual Conformal Coupling Monitor (ICCM), a pre-inference method to detect structural ambiguity in wearable stress classification, improving safety by routing uncertain signals for abstention or deferral.
This paper presents a longitudinal multimodal study of 66 older adults using wearable sensing and clinical assessments to predict physical activity, sleep duration, and sleep apnea severity, finding that behavioral targets are more predictable and historical features are key predictors.
