Classification of Heart Sounds Using Convolutional Neural Network

Applied Sciences, 2020
Heart sounds play an important role in the diagnosis of cardiac conditions. Due to the low signal-to-noise ratio (SNR), it is problematic and time-consuming for experts to discriminate different kinds of heart sounds.

Biometric Identification Method for Heart Sound Based on Multimodal Multiscale Dispersion Entropy

Entropy, 2020
In this paper, a new method of biometric characterization of heart sounds based on multimodal multiscale dispersion entropy is proposed. Firstly, the heart sound is periodically segmented, and then each single-cycle heart sound is decomposed into a group
