. Although deep learning-based current methods have achieved impressive results in electrocardiograph (ECG) arrhythmia classification issues, they rely on using the original data to identify arrhythmia categories. However, a large amount of data generated by long-term ECG monitoring pose a significant challenge to the limited-bandwidth and real-time systems, which limits the application of deep learning in ECG monitoring.. This paper, therefore, proposed a novel multi-task network that combined compressed sensing and convolutional neural networks, namely CSML-Net. According to the proposed model, the ECG signals were compressed by utilizing a learning measurement matrix and then recovered and classified simultaneously via shared layers and two task branches. Among them, the multi-scale feature module was designed to improve model performance.. Experimental results on the MIT-BIH arrhythmia dataset demonstrate that our proposed method is superior to all the approaches that have been compared in terms of reconstruction quality and classification performance.. Consequently, the proposed model achieving the reconstruction and classification in the compressed domain can be an improvement and become a promising approach for ECG arrhythmia reconstruction and classification.
虽然基于深度学习的现有方法在心电图(ECG)心律失常分类问题上取得了令人瞩目的成果,但它们依赖于使用原始数据来识别心律失常类别。然而,长期 ECG 监测产生的大量数据对有限带宽和实时系统构成了重大挑战,这限制了深度学习在 ECG 监测中的应用。因此,本文提出了一种新颖的结合压缩感知和卷积神经网络的多任务网络,即 CSML-Net。根据所提出的模型,利用学习测量矩阵对 ECG 信号进行压缩,然后通过共享层和两个任务分支同时进行恢复和分类。其中,设计了多尺度特征模块以提高模型性能。在 MIT-BIH 心律失常数据集上的实验结果表明,与所有已比较的方法相比,我们提出的方法在重建质量和分类性能方面都具有优势。因此,该模型在压缩域中实现重建和分类的能力是一种改进,为 ECG 心律失常的重建和分类提供了一种有前途的方法。
