Regression tree pruning reduces the risk of overfitting by verifying the predictive utility of all nodes of a regression tree. PEP - Policy Enforcement Point.

In this paper, we developed highly accurate ensemble machine learning models integrating Reduced Error Pruning Tree (REPT) as a base classifier with the.

Reduced Error Pruning is an algorithm that has been used as a representative technique in attempts to explain the problems of decision tree learning. Pruning removing the subtree at that node, make it a leaf and assign the most common class at that node A node is removed if the resulting tree performs no worse then the original on the validation set - removes coincidences and errors. .

Pruning is a data compression technique in machine learning and search algorithms that reduces the size of decision trees by removing sections of the tree that are non-critical and redundant to classify instances. maxdepthint, defaultNone.
