Gradient Boosted Regression Trees. The Gradient Boosted Regression Trees (GBRT) model (also called Gradient Boosted Machine or GBM) is one of the most effective machine learning models for predictive analytics, making it an industrial workhorse for machine learning. Background. The Boosted Trees Model is a type of additive model that makes predictions by combining decisions from a sequence of base models. More formally we can write this class of models as: where the final classifier is the sum of simple base classifiers . For boosted trees model, each base classifier is a simple decision tree. This broad technique of using multiple models to obtain better predictive performance is called model ensembling. Unlike Random Forest which constructs all the base classifier independently, each using a subsample of data, GBRT uses a particular model ensembling technique called gradient boosting.
