Soft Voting Ensemble- Based Approach for Diagnosing Diabetes Mellitus

Millions of people worldwide have dia-betes, a severe health condition characterized by high levels of glucose in the blood that can lead to various complications. Early detection and prediction are cru-cial in managing the disease effectively. In this study, we utilized a soft voting, ensemble-based approach to improve the accuracy of predicting diabetes mellitus. The dataset comprised medical records and laboratory analyses of 1000 diabetic patients collected from two hospitals in Iraq. The study utilized an ensemble method with a soft voting classifier comprising Random Forest, XGBoost, and Gradient Boosting to achieve binary classification. The ensemble model achieved an impressive accuracy of 99.50% on the Iraqi diabetes dataset, with precision, recall, and F1-score values of 99.52%, 99.50%, and 99.51 %, respectively. This re-search highlights the effectiveness of ensemble learning in improving the predictive power of machine learning models for diabetes detection.
