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...

An experiment was conducted to determine the best iteration that could model hourly PM10 concentrations by optimizing the BRT parameter which are learning rate (lr), tree complexity (tc) and number of trees (nt). Five different lr (0.001, 0.005, 0.01, 0.05 and 0.1) were tested with ...
The final BRT model can be understood as an additive regression model in which individual terms are simple trees, fitted in a forward, stagewise fashion. Boosted regression trees incorporate important advantages of tree-based methods, handling different types of predictor variables and accommodating ...
The algorithm extends Freidman's L2-tree-boosting framework to latent variable models. In a simulation study, we compare this approach, which we call OD-BRT, to the standard logistic regression formulation of the OD model and to a purely predictive approach: boosted regression trees (BRT) ...
