“…In [ 18 ], various machine learning algorithms including neural networks, decision trees, random forest, gradient boosting, and SVM are used for arrhythmia classification after applying rigorous preprocessing and feature selection techniques on ECG data. Similarly, OneR, J48, Naïve Bayes, SVM, logistic regression, KNN, random forest, and decision trees have been applied on ECG medical dataset to classify arrhythmia into 16 different classes [ 19 – 21 ]. Significant work on ECG dataset is conducted presenting SVM based methods for detecting arrhythmia with selection of significant features using principal component analysis [ 22 , 23 ].…”
