  Evaluating Traditional Machine Learning Models for Predicting Diabetes Onset Using the Pima Indians Dataset
  Author(s): Faith Nassiwa* and Jiahui Zeng
  
  Diabetes is a leading disease in the world. With the seriousness of diabetes and its complexity in diagnosis, we aimed to produce a model to help with prediction of onset of diabetes. Three models, logistic regression, gradient boosting and random forest were performed and evaluated to predict the onset of diabetes. A dataset of size 768 that includes information about some indian population were used. the population are specific to indian women that are at least 21 years old and of Pima Indian Heritage. Methods of standardizing including Synthetic Minority Oversampling Technique (SMOTE) and hyperparameter tuning are performed. Random forest performed the best with an accuracy score of 81.8%, followed by gradient boosting (78%), and followed by logistic regression (76%). Glucose, BMI and age are the top predictors for Diabetes according to random forest.. Read More»
