“…According to their results, the decision tree outperforms the other algorithms. In addition, the authors [22] have used ML models based on bagging and boosting, employed ensemble-based models, such as RF, Extra Trees, Gradient Boosting, AdaBoost, and Extreme Gradient Boosting, to predict the daily vaccination rate in the world. The Extra Trees algorithm shows better results, i.e., minimized MAE of 6.465 and RMSE of 8.127.…”
