Decision Tree Pruning Alpha at Merilyn Tabor blog

Decision Tree Pruning Alpha. In decisiontreeclassifier, this pruning technique is parameterized by the cost complexity parameter, ccp_alpha. Greater values of ccp_alpha increase the number of nodes. It says we apply cost. Decisiontree in sklearn has a function called cost_complexity_pruning_path, which gives the effective alphas of subtrees during pruning and also the corresponding impurities. Decisiontree in sklearn has a function called cost_complexity_pruning_path, which gives the effective alphas of subtrees during pruning and also the corresponding impurities. In the following lectures tree methods, they describe a tree algorithm for cost complexity pruning on page 21. Decision tree pruning removes unwanted nodes from the overfitted decision tree to make it smaller in size which results in more fast, more accurate and more effective. How does cost complexity pruning or ‘weakest link pruning’ work? It may also provide no performance improvement at all, depending on how unlucky you are.
