Survey on Sequential Pattern Mining based on User - Constraints

open access: yesTạp chí Phát triển và Hội nhập, 2023
Sequence data mining, also known as sequential pattern mining, is to find all frequent sub-sequences (called sequential patterns) in a sequence database, the threshold of frequency is specified by the user.

Learning Sequential Patterns for Lipreading [PDF]

open access: yesProcedings of the British Machine Vision Conference 2011, 2011
This paper proposes a novel machine learning algorithm (SP-Boosting) to tackle the problem of lipreading by building visual sequence classifiers based on sequential patterns. We show that an exhaustive search of optimal sequential patterns is not possible due to the immense search space, and tackle this with a novel, efficient tree-search method with a

Discovering Sequential Source Code Patterns in Software Engineering

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2022
Discovering sequential patterns in source codes is an important issue in software engineering since it can provide useful knowledge to help in a variety of tasks such as code completion, code refactoring, developer profiling, and code complexity ...

Mapping Background Variables With Sequential Patterns in Problem-Solving Environments: An Investigation of United States Adults’ Employment Status in PIAAC

open access: yesFrontiers in Psychology, 2019
Adult assessments have evolved to keep pace with the changing nature of adult literacy and learning demands. As the importance of information and communication technologies (ICT) continues to grow, measures of ICT literacy skills, digital reading, and ...

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.

Semantics of Negative Sequential Patterns

open access: yes, 2020
In the field of pattern mining, a negative sequential pattern is specified by means of a sequence consisting of events to occur and of other events, called negative events, to be absent. For instance, containment of the pattern $\langle a\ \neg b\ c\rangle$ arises with an occurrence of a and a subsequent occurrence of c but no occurrence of b in ...

Dichotomic Pattern Mining Integrated With Constraint Reasoning for Digital Behavior Analysis

open access: yesFrontiers in Artificial Intelligence, 2022
Sequential pattern mining remains a challenging task due to the large number of redundant candidate patterns and the exponential search space. In addition, further analysis is still required to map extracted patterns to different outcomes. In this paper,

Contextual Sequential Pattern Mining [PDF]

open access: yes2010 IEEE International Conference on Data Mining Workshops, 2010
Traditional sequential patterns do not take into account additional contextual information since patterns extracted from data are usually general. By considering the fact that a pattern is associated with one specific context the decision expert can then adapt his strategy considering the type of customers. In this paper we propose to mine more precise

A review on big data based parallel and distributed approaches of pattern mining

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
Pattern mining is a fundamental technique of data mining to discover interesting correlations in the data set. There are several variations of pattern mining, such as frequent itemset mining, sequence mining, and high utility itemset mining. High utility
