Abstract
Machine learning methodologies have gained attention in classifying clinical problems in recent years. Coronary heart disease is a significant clinical problem to be addressed and classified using machine learning strategies. The outliers should be handled better to improve the model’s overall performance. Our research work proposed two different methods to avoid outliers from the data set. Feature selection from the dataset was made through the mutual information-based feature selection to compute the relevant set of features from the Bio image of heart through electrocardiographic signals. The outlier in the data has been reduced and classification is done using proposed isolation forest. Normalization is adopted to minimize misclassification, which has improved the overall accuracy, specificity, and sensitivity of the proposed machine learning model from the existing algorithm. A benchmark coronary dataset that has 303 data samples and 76 features had been utilized for research purposes.
