Diabetes is a problematic condition all over the world, and it has huge impact on global population and healthcare budgets. Diabetes is a long-term illness that impairs the body’s ability to properly regulate blood sugar, and the search for efficient methods of early diagnosis is still relevant now. This project is the proposal of artificial neural network in examining diabetic disease using clinical characteristics. The proposed system utilizes a low cost and effective technique for data analysis in context with medical data-driven diagnosis for possibility of developing diabetes. The framework requires clinical aspects including blood glucose level, blood pressure, BMI, insulin levels and family medical history for the assessment of tested models. That way, the system offers high accuracy and reliability—thanks to algorithms like gradient boosting classifier, SVM and KNN. The application of feature selection approaches ensures that only useful indicator domains are chosen, to minimize computational costs as well as improve model interpretability. The gradient boosting algorithm significantly improved the results in our diabetes detection, showcasing the effectiveness of predictive modelling in health care. The accuracy score received by gradient boosting algorithm is 91.45, which is best compared to other algorithms. Based on this analysis, ML does have the capability to revolutionize diabetes diagnosis which in return offers wider and more accurate proactive healthcare systems. Tentative developments include incorporating real-time monitoring devices into the models in the future and expanding their applications to other chronic diseases, which can result in holistic and sustainable healthcare programs.
