Towards Target High-Utility Itemsets
In this paper, we address this issue by proposing a novel list-based algorithm with pattern matching mechanism, named THUIM (Targeted High-Utility Itemset Mining), which can quickly match high-utility itemsets during the mining process to select the targeted patterns.
TargetUM: Targeted High-Utility Itemset Querying
The algorithm uses a lexicographic querying tree and three effective pruning strategies to improve the mining efficiency.
