Abstract
Psychological stress in human beings has been on a meteoric rise over the last few years. Chronic stress can have fatal consequences such as heart disease, cancer, suicide and so on. It is thus imperative to detect stress early on to prevent health risks. In this work, we discuss efficient and accurate stress and affect detection using scalable Deep Learning methods, that can be used to monitor stress real-time on resource-constrained devices such as low-cost wearables. By making inferences on-device, we solve the issues of high latency and lack of privacy which are prevalent in cloud-based computation. Using the concept of Early Stopping - Multiple Instance Learning, we build specialized models for stress and affect detection for 3 popular datasets in the domain, that have very low inference times but high accuracy. We introduce a metric ηcomp to measure the computational savings from the use of these models. On average, our models show an absolute increase of 10% in overall accuracy over the benchmarks, computational savings of 95.39%, and an 18x reduction in inference times on a Raspberry Pi 3 Model B. This allows for efficient and accurate real-time monitoring of stress on low-cost resource-constrained devices.
在过去的几年里,人类的心理压力一直在迅速上升。慢性压力会导致致命的后果,比如心脏病、癌症、自杀等等。因此,必须及早发现压力,以预防健康风险。在这项工作中,我们讨论了使用可扩展的深度学习方法进行有效和准确的压力和影响检测,该方法可用于实时监测资源受限设备(如低成本可穿戴设备)的压力。通过在设备上进行推断,我们解决了在基于云的计算中普遍存在的高延迟和缺乏隐私的问题。利用早期停止-多实例学习的概念,我们为该领域的3个流行数据集建立了专门的压力和影响检测模型,这些模型具有非常低的推理时间但精度很高。我们引入了一个度量η比较来衡量使用这些模型所节省的计算量。平均而言,我们的模型显示,与基准测试相比,总体精度绝对提高了10%,计算节省了95.39%,在Raspberry Pi 3 Model b上的推理时间减少了18倍。这允许在低成本资源受限的设备上高效、准确地实时监测压力。
