DryadeParent, An Efficient and Robust Closed Attribute Tree Mining Algorithm
Résumé
In this paper we present a new tree mining algorithm, DryadeParent, based on the hooking principle first introduced in Dryade. In the experiments, we demonstrate that the branching factor and depth of the frequent patterns to find are key factors of complexity for tree mining algorithm, even if often overlooked in previous work. We show that DryadeParent outperforms the current fastest algorithm, CMTreeMiner, by orders of magnitude on datasets where the frequent tree patterns have a high branching factor.
