In a decision tree, a dataset is sequentially divided through a series of splits into smaller sets to reduce variance.
WebJan 20, 2024 · The Boosted regression trees (BRT) technique is an improvement of the regression trees model. BRT uses a boosting technique to combine decisions from a sequence of base models to enhance the accuracy of the final model (Elith et al., 2008 ; Naghibi et al., 2016 ; Yang et al. 2016 ).
