Efficient Chain Structure for High-Utility Sequential Pattern Mining [PDF]

open access: yesIEEE Access, 2020
High-utility sequential pattern mining (HUSPM) is an emerging topic in data mining, which considers both utility and sequence factors to derive the set of high-utility sequential patterns (HUSPs) from the quantitative databases.

Sequential Hierarchical Pattern Clustering [PDF]

open access: yes, 2009
Clustering is a widely used unsupervised data analysis technique in machine learning. However, a common requirement amongst many existing clustering methods is that all pairwise distances between patterns must be computed in advance. This makes it computationally expensive and difficult to cope with large scale data used in several applications, such ...

Sequential patterns for text categorization [PDF]

open access: yesIntelligent Data Analysis, 2006
Text categorization is a well-known task based essentially on statistical approaches using neural networks, Support Vector Machines and other machine learning algorithms. Texts are generally considered as bags of words without any order. Although these approaches have proven to be efficient, they do not provide users with comprehensive and reusable ...

Towards bounding sequential patterns [PDF]

open access: yesProceedings of the 17th ACM SIGKDD international conference on Knowledge discovery and data mining, 2011
Given a sequence database, can we have a non-trivial upper bound on the number of sequential patterns? The problem of bounding sequential patterns is very challenging in theory due to the combinatorial complexity of sequences, even given some inspiring results on bounding itemsets in frequent itemset mining.

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
