Mining High Utility Itemsets with Regular Occurrence
High utility itemset mining (HUIM) plays an important role in the data mining community and in a wide range of applications. For example, in retail business it is used for finding sets of sold products that give high profit, low cost, etc. These itemsets

Efficient Algorithm for Mining Non-Redundant High-Utility Association Rules
In business, managers may use the association information among products to define promotion and competitive strategies. The mining of high-utility association rules (HARs) from high-utility itemsets enables users to select their own weights for rules ...

Mining High-Efficiency Itemsets with Negative Utilities
High-efficiency itemset mining has recently emerged as a new problem in itemset mining. An itemset is classified as a high-efficiency itemset if its utility-to-investment ratio meets or exceeds a specified efficiency threshold.

An efficient strategy for mining high utility itemsets
Methods for mining high utility itemsets from databases have been discussed widely in recent years. They mine itemsets having high utility from databases. Pruning candidates based on transaction-weighted utilisation value is a good method at all. In this paper, we develop a tree structure called WIT-tree, and use it in the proposed TWU-mining algorithm,

MINING OF HIGH-UTILITY ITEMSETS WITH NEGATIVE UTILITY
The goal of the high-utility itemset mining task is to discover combinations of items that yield high profits from transactional databases. HUIM is a useful tool for retail stores to analyze customer behaviors. However, in the real world, items are found with both positive and negative utility values.

Selective Database Projections Based Approach for Mining High-Utility Itemsets
High-utility itemset mining (HilIM) is an emerging area of data mining and is widely used. HilIM differs from the frequent itemset mining (FIM), as the latter considers only the frequency factor, whereas the former has been designed to address both ...

Effective Utility Mining with the Measure of Average Utility
[[abstract]]Frequent-itemset mining only considers the frequency of occurrence of the items but does not reflect any other factors, such as price or profit.
