WebA full-grown tree combines the decisions from all variables to predict the target value. A stump, on the other hand, can only use one variable to make a decision. Let's try and understand the behind-the-scenes of the AdaBoost algorithm step-by-step by looking at several variables to determine whether a person is "fit" (in good health) or not. WebBoosted Tree Regression Model in R. To create a basic Boosted Tree model in R, we can use the gbm function from the gbm function.
