Efficient algorithms for discovering high-utility patterns with strong frequency affinities

Expert systems with applications, 2021
In recent years, high-utility pattern mining has been studied extensively. However, most of these studies have addressed mining high-utility patterns (HUPs) without consideration for their frequencies, leading to the mining of meaningless HUPs.

Efficient list based mining of high average utility patterns with maximum average pruning strategies

Information Sciences, 2021
High average utility pattern mining is the concept proposed to complement drawbacks of high utility pattern mining by considering lengths of patterns along with the utilities of the patterns.

SOHUPDS: a single-pass one-phase algorithm for mining high utility patterns over a data stream

ACM Symposium on Applied Computing, 2020
High utility pattern mining has emerged to overcome the limitation of frequent pattern mining where only frequency is taken as importance without considering the actual importance of items. Existing algorithms for mining high utility patterns over a data

An indexed set representation based multi-objective evolutionary approach for mining diversified top-k high utility patterns

Engineering Applications of Artificial Intelligence, 2019
How to discover top-k patterns with the largest utility values, namely, mining top-k high utility patterns, is a hot topic in data mining. However, most of the existing works for mining top-k high utility patterns consider each pattern separately during ...
