網頁2024年2月15日 · The CART algorithm recognizes candidate subtrees through a procedure of repeated pruning. The objective is to prune first those branches supporting the least more predictive power per leaf. It can recognize these least beneficial branches, CART based on a concept known as the adjusted error rate. 網頁Understand the difference between CART and DecisionTreeClassifier of Sklearn. In Sklearn's documentation, it says that " scikit-learn uses an optimised version of the CART algorithm ". However, I couldn't find what this optimisation was anywhere!
