To design these models, we used four machine learning algorithms, i.e. K nearest neighbors KNN, Decision trees DT, Support Vector Machine SVM, and Logistic Regression LR. The performance of the obtained models was tested according to the accuracy of each model. The highest accuracy rates were obtained in the decision tree model in both the split method (Train / Test Split) and k_fold cross validation splitting model.
