This failure is due to the inappropriate implementation of WatSan technologies and the lack of decision-making resources. This study explores the application of several machine learning classification algorithms to predict the optimal WatSan system effectively. The proposed classification methods are Logistic Regression, Random Forest, Support Vector Machine, CatBoost, and Neural Network. The practicality of these classification methods was tested using a dataset comprising 774 water technology options. Several experiments were conducted to obtain the highest possible classification accuracy of the capacity requirement level (CRL) in terms of accuracy and F1 score classification metrics. Our findings suggest that CatBoost, with the addition of the synthetic minority oversampling technique (SMOTE), outperforms the other algorithms in classifying WatSan technology options.http://creativecommons.org/licenses/by/4.0/Water1515Al Nuaimi_et_al_Water_15(15)_2023.pdfChania [Greece]Library of TUC2025-07-18application/pdf2.2 MBfree Al Nuaimi Hala Abdelmagid Mohamed Bouabid Ali Chrysikopoulos Constantinos Χρυσικοπουλος Κωνσταντινος Maalouf Maher MDPI Classification Decision support system Logistic Regression Machine learning Random Forest Support Vector Machine
