Are there situations where a shallow tree can still be very complex? Discuss the interaction between max depth and the handling of categorical features with many levels (high cardinality).

By default a tree of maximum depth of 2 is fitted to improve interpretability. To learn more about global surrogate models, read the Interpretable Machine ... A depth of 1 means 2 terminal nodes. Depth of 2 means max. 4 nodes. Depth of 3 means max. 8 nodes. The maximum number of terminal nodes in a binary tree is 2 ... Nov 25, 2017 ... The thumb rule is to have a max depth of roughly log (base 2) of number of attributes. So if you indeed have tree(s) with depth 17000 (!!!), you are getting ...

You also can use max_depth to limit the tree depth explicitly. If you set ... Three consecutive images of decision trees, where each shows the tree with an ... You will tune the max_depth parameter of the decision tree to discover the one which reduces over-fitting while still maintaining good model performance ... It supports a maximum depth constraint and a minimum support constraint, but only works for binary classification tasks. It also relies on branch-and-bound ...
