Controlling tree growth in XGBoost
In addition to limiting the maximum depth of trees using a max_depth hyperparameter, there is another paradigm for controlling tree growth: finding the node where a split would result in the greatest reduction in the loss function, and splitting this node, regardless of how deep it will make the tree. This may result in a tree with one or ...
