Efficient approach for incremental high utility pattern mining with indexed list structure

Future generations computer systems, 2019
Since traditional frequent pattern mining approaches assume that all the items in binary databases have the same importance regardless of their own features, they have difficulty in satisfying requirements of real world applications such as finding ...

High Utility Partial Periodic Pattern Mining

Proceedings of the 4th Multidisciplinary International Social Networks Conference, 2017
In this paper, we study the properties of partial periodic pattern mining and extend the original problem to high-utility partial periodic pattern mining (HUPPP), which considers not only the occurring time order and periodic length of events but also the quantities and individual profits of the events.

ProUM: High Utility Sequential Pattern Mining

2019 IEEE International Conference on Systems, Man and Cybernetics (SMC), 2019
In recent decade, utility mining has attracted a great attention, but most of the existing studies are developed to deal with itemset-based data. Different from the itemset-based data, the time-ordered sequence data is more commonly seen in real-world situations.

Mining High Utility Sequential Patterns Using Multiple Minimum Utility

International Journal of Pattern Recognition and Artificial Intelligence, 2018
High utility sequential patterns (HUSP) mining has recently received a lot of attention from researchers. Many algorithms have been proposed to mine HUSP and most of them only use a single minimum utility, which implicitly assumes that all items in the database are of the same importance (such as profit), or other information based on users’ concern ...

Large-Scale High-Utility Sequential Pattern Analytics in Internet of Things

IEEE Internet of Things Journal, 2021
The concepts of sequential pattern mining have become a growing topic in data mining, finding a home most recently in the Internet of Things (IoT) where large volumes of data are presented by the second for analysis and knowledge extraction.

Exploiting High Utility Occupancy Patterns

2017
Most studies have considered the frequency as sole interestingness measure for identifying high quality patterns. However, each object is different in nature, in terms of criteria such as the utility, risk, or interest. Besides, another limitation of frequent patterns is that they generally have a low occupancy, and may not be truly representative ...

Efficient incremental high utility pattern mining based on pre-large concept

Engineering applications of artificial intelligence, 2018
High utility pattern mining has been actively researched in recent years, because it treats real world databases better than traditional pattern mining approaches.

Mining Discriminative High Utility Patterns

2016
Recently, many approaches for high utility pattern mining (HUPM) have been proposed, but most of them aim at mining high-utility patterns (HUPs) instead of frequent ones. The major drawback is that any combination of a low-utility item with a very high utility pattern is regarded as a HUP, even if this combination is infrequent and contains items that ...

Scalable and Efficient Approach for High Temporal Fuzzy Utility Pattern Mining

IEEE Transactions on Cybernetics, 2022
Fuzzy utility (FU) pattern mining with an advantage in human reasoning has become one of the interesting topics in studies of knowledge discovery. The discovered information in FU pattern mining from real-life quantitative databases with item profits is ...

Two Sliding Window Control Based High Utility Pattern Mining

International Conference on Computing Communication Control and automation, 2018
Value of the item set is considered as a utility of that item set and find out the high utility of the item set is the aim of utility mining. Some time database parameters are considered to find out high utility pattern eg. Profit, cost etc.
