Incremental Mining of High Utility Patterns in One Phase by Absence and Legacy-Based Pruning

open access: yesIEEE Access, 2019
Mining high utility patterns in dynamic databases is an important data mining task. While a naive approach is to mine a newly updated database in its entirety, the state-of-the-art mining algorithms all take an incremental approach. However, the existing

Mining High Utility Itemsets Based on Pattern Growth without Candidate Generation

open access: yesMathematics, 2020
Mining high utility itemsets (HUIs) has been an active research topic in data mining in recent years. Existing HUI mining algorithms typically take two steps: generating candidates and identifying utility values of these candidate itemsets.

EHAUPM: Efficient High Average-Utility Pattern Mining With Tighter Upper Bounds

open access: yesIEEE Access, 2017
High-utility itemset mining (HUIM) has become a popular data mining task, as it can reveal patterns that have a high-utility, contrarily to frequent pattern mining, which focuses on discovering frequent patterns.

An Efficient Tree-Based Algorithm for Mining High Average-Utility Itemset

open access: yesIEEE Access, 2019
High-utility itemset mining (HUIM), which is an extension of well-known frequent itemset mining (FIM), has become a key topic in recent years. HUIM aims to find a complete set of itemsets having high utilities in a given dataset.

Utility-driven Mining of Contiguous Sequences

open access: yesCoRR, 2021
Recently, contiguous sequential pattern mining (CSPM) gained interest as a research topic, due to its varied potential real-world applications, such as web log and biological sequence analysis. To date, studies on the CSPM problem remain in preliminary stages.

Association Mining for Super Market Sales using UP Growth and Top-K Algorithm [PDF]

open access: yesITM Web of Conferences, 2020
Frequent itemsets(HUIs) mining is an evolving field in data mining, that centers around finding itemsets having a utility that meets a user-specified minimum utility by finding all the itemsets.

Efficient Method for Mining High Utility Occupancy Patterns Based on Indexed List Structure

open access: yesIEEE Access, 2023
High utility pattern mining has been proposed to improve the traditional support-based pattern mining methods that process binary databases. High utility patterns are discovered by effectively considering the quantity and importance of items.
