Forest Pruning Based on Branch Importance

Table 3

The ranks of algorithms using Friedman test, where Alg1, Alg2, Alg3, Alg4, Alg5, and Alg6 indicate PF pruning bagging with unpruned C4.5, bagging with unpruned C4.5, PF pruning bagging with pruned C4.5, bagging with pruned C4.5, PF pruning random forest, and random forest.

Algorithm	Alg5	Alg3	Alg1	Alg2	Alg6	Alg4
Ranks	2.39	2.50	2.71	4.32	4.42	4.66
