Webapproach to SMOTE, a popular over-sampling technique [9]. SMOTE has historically been used as a pre-processing step at the front-end of single layer ML models. In DeepSMOTE [40], the authors incorporated SMOTE over-sampling into deep networks through the use of an auto-encoder trained with a reconstruction plus a penalty loss. WebThe experimental results showed that XGB classifier ranked as the best algorithm for viral load prediction in terms of sensitivity (97%), f1-score (96%), AUC (0.99), accuracy (96%), followed by RF. The GB classifier exhibited a better predictive capability in predicting participants with a CD4 cell count < 200 cells/mL. WebHowever, the integration of ensemble classifiers into health systems in many developing countries is still nascent. Therefore, this study applied SMOTE, SMOTEEN and SMOTETomek class imbalance approaches and ensemble ML classifiers to predict diarrhoea.
