How does max depth interact with different loss functions used in regression trees? What are the computational trade-offs between training a shallow versus a deep decision tree on a large dataset?

Find the optimal depth for the Decision Tree model and evaluate performance. ... reshape(-1,)) print("Decision Tree max depth {:}".format(best_depth)) print ... ... tree depth of 1 (J. Friedman, Hastie, and Tibshirani 2001). Smaller depth trees such as decision stumps are computationally efficient (but require more trees); ... Aug 21, 2019 ... Tree depth is a measure of how many splits a tree can make before coming to a prediction. This process could be continued further with more ... `learning_rate` that determines the contribution of each tree; `n_estimatorst` dictates the number of decision trees; `max_depth` is the maximum depth of each ...
