Calibration, not architecture, limits cross-subject wearable stress detection: a multi-dataset, decision-focused evaluation with label-efficient recalibration

Continuous wearable stress monitoring could support early intervention and self-management, but a stress estimate is useful only if it can guide a decision, which requires calibrated probabilities with demonstrable decision value, not discrimination. Most wearable stress studies have emphasised discrimination and...
