An Algorithm for Mining High Utility Sequential Patterns with Time Interval

open access: yesCybernetics and Information Technologies, 2019
Mining High Utility Sequential Patterns (HUSP) is an emerging topic in data mining which attracts many researchers. The HUSP mining algorithms can extract sequential patterns having high utility (importance) in a quantitative sequence database.

Dramatically Reducing Search for High Utility Sequential Patterns by Maintaining Candidate Lists

open access: yesInformation, 2020
A ubiquitous challenge throughout all areas of data mining, particularly in the mining of frequent patterns in large databases, is centered on the necessity to reduce the time and space required to perform the search.

HUIL-TN & HUI-TN: Mining high utility itemsets based on pattern-growth.

open access: yesPLoS ONE, 2021
In recent years, high utility itemsets (HUIs) mining has been an active research topic in data mining. In this study, we propose two efficient pattern-growth based HUI mining algorithms, called High Utility Itemset based on Length and Tail-Node tree ...

Particle-scale structure in frozen colloidal suspensions from small angle X-ray scattering [PDF]

open access: yes, 2010
During directional solidification of the solvent in a colloidal suspension, the colloidal particles segregate from the growing solid, forming high-particle-density regions with structure on a hierarchy of length scales ranging from that of the particle ...

Ecological validity of a simplified version of the multiple errands shopping test [PDF]

open access: yes, 2003
Shallice and Burgess (1991) reported the utility of the Multiple Errands Test (MET) in discriminating executive deficits in three frontal lobe patients with preserved high IQ, who were otherwise unimpaired on tests of executive function.

Fast Single Pbase Algoritbm for Utility Mining in Big Data

open access: yesDianxin kexue, 2015
Most of the latest works on utility mining generates a huge number of candidates in dealing with big data,which suffers from the scalability issue.Some work does not generate candidates,but suffers from the efficiency issue due to lack of strong pruning ...

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.

Mining of high utility-probability sequential patterns from uncertain databases. [PDF]

open access: yesPLoS ONE, 2017
High-utility sequential pattern mining (HUSPM) has become an important issue in the field of data mining. Several HUSPM algorithms have been designed to mine high-utility sequential patterns (HUPSPs).
