Abstract
Despite numerous advancements in modern medicine, cardiovascular diseases still rank among the top mortality factors all around the world, with 18 million annual deaths caused by heart diseases according to the World Health Organization estimates. Identification of individuals with elevated risk of heart diseases is important in order to reduce the mortality rate especially in developing countries with limited access to medical facilities. Thanks to recent progress made in Artificial Intelligence and Machine Learning, it became possible to create intelligent diagnostic systems that can help doctors diagnose patients at an early stage. This paper aims at evaluating the performance of five supervised machine learning algorithms for heart disease prediction, namely, Random Forest, Support Vector Machine, Logistic Regression, Decision Tree, and K-Nearest Neighbors. Based on experimental evaluation, the Random Forest algorithm shows the best performance providing an accuracy of 90.16% while logistic regression shows accuracy of 85.25%, and the KNN classifier shows the lowest accuracy level of 67.21%. In addition to classification accuracy, the precision and recall values are also estimated based on the confusion matrix. The achieved results suggest that ensembles of learning algorithms provide better predictions while maintaining appropriate level of generalization.
