Introduction. Pruning is a technique in machine learning that involves diminishing the size of a prepared model by eliminating some of its parameters. The objective of pruning is to make a smaller, faster, and more effective model while maintaining its accuracy.When applied on a decision tree, the splitter algorithm is applied to each node and each feature. Note that each node receives ~1/2 of its parent examples. Therefore, according to the master theorem, the time complexity of training a decision tree with this splitter is:
