"WebIn general, it is good to keep the lower bound on the range of values close to one. There are many cases where random forests with a max depth of one have been shown to be highly effective. The upper bound on the range of values to consider for max depth is a little more fuzzy. In general, we recommend trying max depth values ranging from 1 to 20. " - Maximal treedepth

Maximal treedepth

WebControls the maximum depth of the tree that will be created. It can also be described as the length of the longest path from the tree root to a leaf. The root node is considered to have a depth of 0. The Max Depth value cannot exceed 30 on a 32-bit machine. The default value is 30. Loss Matrix. Weighs the outcome classes differently. Min Bucket. Webtreedepth 0; a matrix with treedepth d ¨0 is either block-diagonal and the maximal treedepth of each block is d, or there exists a row such that deleting this row leads to a matrix of treedepth d ¡1. In terms of treedepth, we also obtain a strongly polynomial algorithm. More precisely, our algorithm requires 2O(d2d)¢O(2d)h1¯o(1)
