摘要:

皮肤电活动(EDA)的测量和分析提供了从市场研究到癫痫发作检测到人体压力分析等不同领域的应用。不幸的是,EDA信号的分析由于许多分量的叠加而变得困难,这些分量会模糊与用户对刺激的响应有关的信号信息。我们展示了如何简单的预处理,然后是一个新的基于压缩感知的分解可以减轻不需要的噪声分量的影响,并帮助揭示潜在的生理信号。建议的框架允许EDA信号的分解与可证明的界限上的用户响应的恢复。我们测试我们的程序从可穿戴传感器的合成和现实世界的EDA信号,并证明我们的方法允许更准确的恢复用户的反应相比,现有的技术。

英文摘要:

The measurement and analysis of Electrodermal Activity (EDA) offers applications in diverse areas ranging from market research, to seizure detection, to human stress analysis. Unfortunately, the analysis of EDA signals is made difficult by the superposition of numerous components which can obscure the signal information related to a user's response to a stimulus. We show how simple pre-processing followed by a novel compressed sensing based decomposition can mitigate the effects of the undesired noise components and help reveal the underlying physiological signal. The proposed framework allows for decomposition of EDA signals with provable bounds on the recovery of user responses. We test our procedure on both synthetic and real-world EDA signals from wearable sensors and demonstrate that our approach allows for more accurate recovery of user responses as compared to the existing techniques.
