Max_depth python
WebIt is important to keep in mind that max_depth is not the same thing as depth of a decision tree. max_depth is a way to preprune a decision tree. In other words, if a tree is already … WebThe decision classifier has an attribute called tree_ which allows access to low level attributes such as node_count, the total number of nodes, and max_depth, the maximal depth of the tree. It also stores the entire binary tree structure, represented as a number of parallel arrays. The i-th element of each array holds information about the node i.
