Interpretable Tsetlin Machine-based Premature Ventricular Contraction Identification

Autor: Zhang, Jinbao, Zhang, Xuan, Jiao, Lei, Granmo, Ole-Christoffer, Qian, Yongjun, Pan, Fan

Neural network-based models have found wide use in automatic long-term electrocardiogram (ECG) analysis. However, such black box models are inadequate for analysing physiological signals where credibility and interpretability are crucial. Indeed, how
