Emotion Recognition Using PPG Signals of Smartwatch on Purpose of Threat Detection

This paper proposes a machine learning approach to detect threats using short-term PPG (photoplethysmogram) signals from a commercial smartwatch. In supervised learning, having accurately annotated training data is essential. However, a key challenge in the threat detection problem is the uncertaint...
