Diabetes, one of the most prevalent chronic diseases worldwide and leads to various serious health problems like heart disease, kidney failure, and nerve damage if not diagnosed and treated in a timely manner. Early recognition is crucial because it may result in a decreased incidence of these complications. This paper investigates the implementation of machine learning (ML) techniques to predict early diabetes. We analyze different models like SVM, RF, GBC, XGB, ABC, and ETC and compare their accuracy, F1-score, specificity, and ROC-AUC. Results show that ensemble models such as XGBoost, Extra Trees Classifier, and Random Forest achieved high accuracy with scores of 99.1%, 99%, and 99%, respectively. In contrast, the AdaBoost Classifier and other models scored only 85.5% accuracy. It has been found from this research that machine learning models are very efficient for early detection of diabetes and ensemble methods have achieved accuracy up to 99%. These findings highlight the promise of machine learning in assisting timely diabetes diagnosis with a significant impact on improving the overall outcomes in healthcare.
