High average-utility itemsets mining: a survey SpringerLink

WebAn itemset in traditional utility mining considers individual profits and quantities of items in transactions regardless of its length. The average-utility measure, which is the total utility of an itemset divided by its number of items within it, was then proposed to reveal a better utility effect than the original utility measure. WebHá 1 dia · These types of methods pay attention to the mining results to maximize the overall benefit. Utility-driven itemset mining (such as Two-Phase [34], HUI-Miner [33], FHM [11]) and utility-driven sequence mining (such as USpan [44], HUS-Span [37], ProUM [14]) have been proposed and have attracted a lot of attention. 2.2.
