Human Heterogeneity Invariant Stress Sensing (HHISS)

Accurately detecting stress using wearable devices is challenging due to significant differences in how individuals respond physiologically to stress. Variations in factors such as heart rate, skin conductance, and environmental conditions can reduce the reliability of stress detection models across different users. Many existing systems are trained on limited datasets and fail to generalize well to new populations, especially in complex cases such as individuals with opioid use disorder. This creates a need for more robust approaches that can deliver consistent performance across diverse users and settings.

 

Researchers at Arizona State University have developed HHISS, a domain generalization framework designed to improve stress detection by using person-wise sub-network pruning and continuous label training. By focusing on shared patterns of stress responses rather than individual differences, HHISS enhances model generalization across diverse populations and environments. The system is particularly effective in challenging use cases, including monitoring stress in individuals with opioid use disorder. This approach enables more reliable and scalable stress detection using wearable devices in real-world conditions. HHISS is an advanced stress detection system that overcomes individual differences to deliver consistent and accurate stress monitoring using wearable devices.
