Sequential Pattern Mining Using IDLists
, 2020 Sequential pattern mining is a practical problem whose objective is to discover helpful informative patterns in a stored database such as market transaction databases. It covers many applications in different areas. Recently, a study that improved the runtime for mining patterns was proposed.

Proceedings of the Eleventh International Conference on Data Engineering, 2002
We are given a large database of customer transactions, where each transaction consists of customer-id, transaction time, and the items bought in the transaction. We introduce the problem of mining sequential patterns over such databases. We present three algorithms to solve this problem, and empirically evaluate their performance using synthetic data.

Mining Compressing Sequential Patterns
Proceedings of the 2012 SIAM International Conference on Data Mining, 2012AbstractPattern mining based on data compression has been successfully applied in many data mining tasks. For itemset data, the Krimp algorithm based on the minimum description length (MDL) principle was shown to be very effective in solving the redundancy issue in descriptive pattern mining.

Sequential Pattern Mining with Wildcards
2010 22nd IEEE International Conference on Tools with Artificial Intelligence, 2010Sequential pattern mining is an important research task in many domains, such as biological science. In this paper, we study the problem of mining frequent patterns from sequences with wildcards. The user can specify the gap constraints with flexibility. Given a subject sequence, a minimal support threshold and a gap constraint, we aim to find frequent

Mining sequential patterns for classification
Knowledge and Information Systems, 2015While a number of efficient sequential pattern mining algorithms were developed over the years, they can still take a long time and produce a huge number of patterns, many of which are redundant. These properties are especially frustrating when the goal of pattern mining is to find patterns for use as features in classification problems. In this paper,

On progressive sequential pattern mining
Proceedings of the 15th ACM international conference on Information and knowledge management - CIKM '06, 2006When sequential patterns are generated, the newly arriving patterns may not be identified as frequent sequential patterns due to the existence of old data and sequences. In practice, users are usually more interested in the recent data than the old ones.

SQUIRE: sequential pattern mining with quantities
Proceedings. 20th International Conference on Data Engineering, 2004In this paper, we consider the problem of mining sequential patterns with quantities. Naive extensions to existing algorithms for sequential patterns are inefficient, as they may enumerate the search space blindly. To alleviate the situation, we propose hash filtering and quantity sampling techniques that significantly improve the performance of the ...

Mining Sequential Patterns with Pattern Constraint
2015Mining sequential patterns is to find the sequential purchasing behaviors for most of the customers. There were many algorithms proposed for discovering all the sequential patterns. However, users may be only interested in certain items or behaviors.

Sequential Pattern Mining: Optimum Maximum Sequential Patterns and Consistent Sequential Patterns
2007 IEEE International Conference on Integration Technology, 2007The concepts of optimal maximum sequential pattern and the consistent sequential pattern are introduced to describe the wholesome characteristics of the sequential pattern mining problems. And a mathematical model and two algorithms are constructed to determine the optimal maximum sequential patterns and the consistent ones.
