How to realize the effect of Kundalini yoga and Chinese Chi meditation on the HRV and ANS with GAN architecture? ‘HRV-GAN’: An alternative approach

Abstract

The alternative approach highlighted in our study ameliorates the process of analyzing the effect on cardiac dynamics due to the practice of Chinese Chi meditation and Kundalini yoga by the implementation of ‘HRV-GAN'. It works by augmenting the dataset of Heart Rate Variability (HRV) signals by 31 times with the aid of the Generative Adversarial Network (GAN) and after that analyzing them without the need for any other equivalent conversion of the signal. The study highlights the distinct effects of practicing different types of meditation on HRV by augmenting the initial dataset entirely in an automated deep learning approach. The visualized results from the architecture are verified statistically. The dataset chosen for the study comprised just 24 meditative HRV samples in total, which have been successfully augmented to 744 samples for classification. The results indicated that meditation affects cardiac dynamics significantly, and diversion varies with the choice of meditation technique. The results obtained from the proposed semi-supervised deep learning model- 'HRV-GAN' was verified statistically by plotting required histograms, Recurrence Plots (RP), and Recurrence Quantification Analysis (RQA) analysis, which were in agreement with each other. HRV-GAN has achieved a sensitivity of 96.667% and an accuracy of 95.556 %. Our innovation can benefit the medical and biomedical community for research involving automated analysis of HRV signals because 'HRV-GAN' can perform appreciably even with fewer data samples for training a deep learning model.
