摘要:

慢性压力会显著影响身心健康。可穿戴技术的出现使得追踪生理信号成为可能,从而有望催生创新的压力预测与干预方法。然而,标签稀缺和数据异质性等挑战使得压力预测在实践中变得困难。为了应对这些问题,我们开发了一个使用可穿戴生物信号数据的多模态个性化压力预测系统。我们采用自监督学习(SSL)对每个受试者的数据进行模型预训练,使模型能够在微调压力预测任务之前学习参与者生物信号的基线动态。我们在可穿戴压力与情感检测(WESAD)数据集上测试了我们的模型,结果表明,我们的SSL模型在仅使用不到5%的标注数据的情况下优于非SSL模型。这些结果表明,我们的方法能够以最少的标注为每个用户实现个性化的压力预测。该范式有潜力利用复杂的多模态数据流实现对多种复发性健康事件的个性化预测。

英文摘要:

Chronic stress can significantly affect physical and mental health. The advent of wearable technology allows for the tracking of physiological signals, potentially leading to innovative stress prediction and intervention methods. However, challenges such as label scarcity and data heterogeneity render stress prediction difficult in practice. To counter these issues, we have developed a multimodal personalized stress prediction system using wearable biosignal data. We employ self-supervised learning (SSL) to pre-train the models on each subject's data, allowing the models to learn the baseline dynamics of the participant's biosignals prior to fine-tuning the stress prediction task. We test our model on the Wearable Stress and Affect Detection (WESAD) dataset, demonstrating that our SSL models outperform non-SSL models while utilizing less than 5% of the annotations. These results suggest that our approach can personalize stress prediction to each user with minimal annotations. This paradigm has the potential to enable personalized prediction of a variety of recurring health events using complex multimodal data streams.
