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...

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...
Briefly, BRT fits a large number of simple regression tree models and applies gradient boosting to assemble them to estimate association between a response variable and a set of predictors (Leathwick et al., 2006). A simple regression tree model partitions observations of the response variable ...
内容提示: Boosted Regression Trees for ecological modelingJane Elith and John LeathwickJune 12, 20111 IntroductionThis is a brief tutorial to accompany a set of functions that we have writtento facilitate f i tting BRT (boosted regression tree) models in R. This tutorial isa modif i ed ...
to understand the tree growth response to ecological and hydroclimatic variability. 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...
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...
