Elevating Accuracy: Enhanced Feature Selection Methods for Type ۲ Diabetes Prediction

Diabetes, a metabolic disorder, poses significant annual risks due to various factors, requiring effective management strategies to prevent life-threatening complications. Classified into Type ۱, Type ۲, and Gestational diabetes, its impact spans diverse demographics, with Type ۲ diabetes being particularly concerning due to cellular insulin deficiencies. Early prediction is crucial for intervention and complication prevention. While machine learning and artificial intelligence show promise in predictive modeling for diabetes, challenges in interpreting models hinder widespread adoption among physicians and patients. The complexity of these models often raises doubts about their reliability and practical utility in clinical settings. Addressing interpretability challenges is crucial to fully harnessing predictive analytics in diabetes management, leading to improved patient outcomes and reduced healthcare burdens. Previous research has utilized various algorithms like Naïve Bayes, Support Vector Machines (SVM), K-Nearest Neighbors (KNN), and decision trees for patient classification. In this study using the Pima dataset, we applied a preprocessing technique that utilized the most important features identified by the Random Forest algorithm and we used an ensemble method combining the SVM algorithm and Naïve Bayes for the model. In the first section of the proposed method, we provided explanations regarding the dataset. In the second section, we elucidated all preprocessing steps applied to this dataset, and in the third section, we evaluated the model using the selected algorithm under investigation. The proposed model, after going through the various stages, was able to report an accuracy of ۸۱.۸۲%, a precision of ۸۲.۳۴%, an AUC of ۸۸.۱۹% and a Recall of ۷۰.۶۸%. Considering the review of similar studies, an improvement of ۳.۹۹% in accuracy demonstrates a significant advancement that highlights the benefits of traditional methods in disease prediction. These findings suggest the potential use of web-based applications to encourage both physicians and patients in diabetes prediction efforts.
