Traditionally, decision trees rank instances by using the local probability estimations for each leaf node. The instances in the same leaf node will be estimated with equal probabilities. In this paper, we propose a hierarchical ranking strategy by combining decision trees and leaf weighted Näıve Bayes to improve the local probability estimation for a leaf node. We consider the importance of th...
