Pruning decision trees is a useful technique for improving the generalization performance in decision tree induction, and for trading accuracy for simplicity in other applications. In this paper, a new algorithm called OPT-2 for optimal pruning of decision trees is introduced. The algorithm is based on dynamic programming. In its most basic form, the time and space complexities of OPT-2 are both...
