Abstract Utility itemsets mining is an extension of frequent itemsets mining,
considering both the quantities of items in the transactions and the
profits of the items. In traditional utility itemsets mining, the
utility of an itemset is the summation of the utilities of the
itemset in all the transactions containing this itemset while
ignoring the length of the itemset and will increase along with an
increase in its length. To eliminate the effect of the length of an
itemset, average utility measurement was proposed, and average
utility of an itemset was defined as the total utility of the
itemset divided by its length. In this article, we propose a
pattern-wise algorithm to mine high average utility itemsets.
Experimental results show that the proposed algorithm outperforms
the existing HAUP-mine algorithm.
