Abstract
Health problems are rising with today’s stressful life, as it promotes cardiac diseases, depression, violence, and may provoke suicide. Hence, it is essential to develop a computer-aided diagnosis system to identify relaxed versus stressed individuals and their correct classification. Heart rate variability (HRV) based on RR interval is a well-proven clinical and diagnostic tool strongly associated with the autonomic nervous system (ANS). In this study, a conventional method was compared with a deep learning-based method. In the Conventional method, features were extracted from various domains, and these features were fed to a classifier to detect stressed states. However, this method uses hand-crafted features, and hence, there is a possibility of missed high potential features that may be responsible for maximizing the classifier’s generalization performance. This work presents a new approach motivated by the long short-term memory network (LSTM) in sequence learning to generate a concrete decision about the signal category. We proposed deep learning-based Inception-LSTM network to improve performance and to reduce computational cost. Two different stress datasets, viz., self-generated stress data and Physionet driver stress data were used to perform the proposed method’s performance analysis. The presented Inception-LSTM architecture outperforms existing literature methods, achieving an accuracy of 93% for self-generated stress data and 97.19% for driver stress data.
