One of the utmost common chronic illnesses in the world, diabetes, must be identified early in order to reduce the hazards to one’s health. Machine learning (ML) models have demonstrated great promise in recent years for increasing the precision and effectiveness of diabetes diagnosis. This study uses a dataset that includes characteristics like age, gender, blood pressure, and body mass index (BMI) to investigate several machine learning algorithms for diabetes diagnosis. The highest goal is to produce a reliable and precise model that can forecast a person’s risk of developing diabetes. A number of models are assessed, such as random forest, support vector machines (SVM), and logistic regression. According to the study, machine learning-based techniques can perform faster and more accurately than conventional methods. With an overall classification accuracy of 85%, the results show that random forest performs enhanced than other replicas. By analyzing the key features influencing diabetes diagnosis, this study emphasizes the potential of machine learning as a valuable tool in healthcare. The implementation of such predictive models can aid medical professionals in identifying high-risk patients, facilitating early intervention and personalized treatment plans.
