ca.pfv.spmf.algorithms.frequentpatterns.hui_miner.AlgoFHM

public class AlgoFHM
extends java.lang.Object

This is an implementation of the "FHM" algorithm for High-Utility Itemsets Mining as described in the conference paper :

Fournier-Viger, P., Wu, C.-W., Zida, S., Tseng, V. (2014) FHM: A Faster High-Utility Itemset Mining Algorithm using Estimated Utility Co-occurrence Pruning. Proc. 21st International Symposium on Methodologies for Intelligent Systems (ISMIS 2014), Springer, LNAI, 12 pages (to appear).
