Özet
Heart diseases are an essential research topic in healthcare institutions around the world. Therefore, using machine learning and optimization algorithms attracts attention as an important method in detecting heart diseases. Additionally, the factors that affect heart disease are a matter of current debate. In this study, an effective DFD method is proposed using optimization techniques for classifying heart diseases and examining the factors affecting the disease. Initially, the study employs classical machine learning and ensemble algorithms for classification. Subsequently, feature selection is performed using BEO, BSPO, GA, and GFO methods, and the importance levels of features are determined utilizing the DFD approach. The results indicate that the ensemble model achieved an accuracy of 86.34% without optimization methods, whereas the proposed DFD method, when applied in conjunction with ensemble models, increased the accuracy to 99.08%. Therefore, it is observed that ensemble models yield the highest results when used in conjunction with optimization algorithms. The outcomes identified using the DFD method, which are clinically significant, are believed to hold great importance in reducing the number of heart patients and enhancing treatment.
