This research investigates the application of XGBoost (Extreme Gradient Boosting) in mining applications, specifically focusing on the use of an adaptive Learned Loss (LL) function to update the loss function during the boosting process. The study aims to demonstrate the effectiveness of XGBoost with...

The readmission prediction model was developed using the extreme gradient boosting (XGboost) model, which can generate an ensemble of classification trees and assign a predictive risk score to each feature. The patient data were split into a training set (5159) and a validation set (911). The ...
To improve tropism prediction accuracy, we developed two novel methods, the extreme gradient boosting based XGBpred and the hidden Markov model based HMMpred. Both XGBpred and HMMpred achieved higher specificities (72.56% and 72.09%) than the state-of-the-art methods Geno2pheno (61.6%) and G...
In the XGBOD framework, various unsupervised anomaly detection models are built and used to transform input variables into the transformed outlier scores (TOSs), and the important TOSs are then selected and added into the original input data to train the extreme gradient boosting (XGBoost) model, ...
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 ...
