Survey on High Utility Itemset Mining

Abstract

Utility-based data mining is a new research area involved in all types of utility factors in data mining processes. The main objective of Utility Mining is to categorize the itemsets with highest utilities, by making an allowance for other user preferences such as quantity, profit and cost.Mining high utility itemsets from a transactional database refers to the encounter of itemsets with high utility like profits. It experience the problem of producing a large number of candidate itemsets used for high utility itemsets. Such a large number of candidate itemsets destroys the mining concert in terms of execution time and space requirement.
