The extreme gradient boosting (XGBoost) is a very efficient and powerful boosting learning algorithm (Chen et al.,2023), which introduces several noteworthy improvements within the gradient boosting framework. As a consequence of the XGBoost, the objective function is further enhanced by including a ...
the eXtreme Gradient Boosting (XGBoost) and CatBoost. The empirical findings indicate the superiority of XGBoost over other advanced machine learning models. Second, it proposes Shapley additive explanations (SHAP) in order to help policy makers to interpret the predictions of complex machine learning ...
The extreme gradient boosting (XGBoost) algorithm proposed by Chen and Guestrin in 2016 is one of the most advanced boosting algorithms, which has not yet been widely used in pavement engineering [48]. Zhan et al. successfully integrated the Fast Fourier Transform (FFT) and XGBoost to predict ...
determined based on a set of questions determining the history of falls and fear of falls. The extreme gradient boosting (XGBoost) model was built from gait features to predict the factor affecting the risk of falls. Moreover, the definition of the fall levels was classified into high- and ...
