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...

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 ...
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...
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...

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 ...
We compared the mechanistic model CLIMEX (CL) with the correlative models MaxEnt (MX), Boosted Regression Trees (BRT), and Random Forests (RF) to project current and future distributions of date palm (Phoenix dactylifera L.). The Global Climate Model (GCM), the CSIRO-Mk3.0 (CS) using the...
