From: Optimal Multi-Stage Arrhythmia Classification Approach
Confusion matrix of GBT model fed by non-rescaled Feature Group 5 dataset of patients with additional conditions. The true class labels of AFIB, GSVT, SB and SR are provided by cardiologists who read the ECGs. The predicted class labels present the outcomes generated by classification model. Numbers in the diagonal line with blue color present the correct prediction. The blue color percentage show the general accuracy of associated category. Compared with confusion matrix shown in Fig. 4, the effect of rescaling the subject’s raw ECG signals to have maximum peak values of 1 has a very small positive effect on the classification accuracy of arrhythmia types.
