    Maximum a posteriori pruning on decision trees and its application to bootstrap BUMPing
    Download  datamining.dongguk.ac.kr
    The cost-complexity pruning generates nested subtrees and selects the best one. However, its computational cost is large since it uses holdout sample or cross-validation. On the o...
