Boosted regression tree (BRT) models, a type of machine learning, were used to predict specific conductance (SC) and chloride (Cl), and total dissolved solids (TDS) was calculated from a correlation with SC. Explanatory variables for BRT models included well location and construction, surficial...

The developed models were constructed based on the boosted regression tree (BRT) and least-squares support vector machine (LSSVM), improved with three metaheuristic algorithms: the gray wolf optimizer (GWO), genetic algorithm (GA), and artificial bee colony (ABC). Six hybrid models, namely BRT...
artificial neural networks (ANN), the adaptive neuro-fuzzy inference system (ANFIS), least-square support vector machine (LS-SVM), and boosted regression tree (BRT) can be utilized to model higher-ordered and non-linear problems more accurately (Mazaheri et al., 2017) (Foroughi et al., 20...

The boosted regression trees (BRT) model, a nonlinear machine learning method, was used to explore the complex relationship between tree-ring growth and climate factors on a larger spatial scale. The common pattern of an asymptotic growth response to the climate indicated that the climate-growth ...
Boosted regression tree (BRT) is a combination of regression tree and boosting [50]. Many decision trees have repeatedly been fitted to the BRT, such as the random forest model, in order to improve the accuracy of the model. There was a difference between the two methods used to construct...

In both examples, boosted decision trees outperformed the linear logistic regression model and the ordinary decision tree with respect to all considered measures of predictive Acknowledgements The study on the mortality in intensive care was partially supported by grant AOM98119 from the clinical research...
Boosted regression treePy/GC-MSThis study investigated the pyrolysis of hemp residue using kinetic analysis . The thermal degradation of hemp residue occurred in three temperature ranges, and the activation energy (E a ) varied between 147.5 kJ/mol and 299.2 kJ/mol depending on the model-free ...
