Mining Conjunctive Sequential Patterns [PDF]
Data Mining and Knowledge Discovery, 2008 In this paper we aim at extending the non-derivable condensed representation in frequent itemset mining to sequential pattern mining. We start by showing a negative example: in the context of frequent sequences, the notion of non-derivability is meaningless. Therefore, we extend our focus to the mining of conjunctions of sequences.

Mining Weighted Sequential Patterns Based on Prefix-Tree and Prism Encoding
Vietnam Journal of Computer Science, 2023 The purpose of mining sequential patterns problem with weighted constraints is to find high-valued patterns, including infrequent patterns but having items which appear in the pattern of high importance in the sequence database (SD).

Sequential patterns for text categorization [PDF]
Intelligent 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 ...

On the use of the Rademacher complexity in mining sequential patterns [PDF]
, 2022 A sequential pattern is a sequence of sets of items. Mining sequential patterns from very large datasets is a fundamental problem in data mining. This thesis formally proves the first rigorous and efficiently computable bound on the Rademacher complexity
