An Introduction to Sequential Pattern Mining The Data

2017-3-8  To do sequential pattern mining, a user must provide a sequence database and specify a parameter called the minimum support threshold. This parameter indicates a minimum number of sequences in which a pattern must appear to be considered frequent, and be shown to the user.

Sequence Mining an overview ScienceDirect Topics

The first sequence mining algorithm was called GSP, which was based on the a priori approach for mining frequent itemsets. GSP makes several passes over the database to count the support of each sequence and to generate candidates. Then, it prunes the sequences with a support count below the minimum support.

A Novel Weighting Technique for Mining Sequence Data

2012-12-11  In this paper, a novel weighting technique for mining interesting sequential patterns over a sequence data stream is proposed. Assuming that a sequence with small time-intervals between its data elements is more valuable than others with large time-intervals, the novel interesting sequential pattern is defined and found by analyzing the time

Process Mining with Sequence Clustering

Sequence clustering is a data mining technique that takes a number of sequences and groups them in clusters so that each clusters contains similar sequences. A sequence is a series of discrete states (Tang 2005), one example is a genomic sequence where the states are adenosine, guanine, cytosine and thymidine. The applicability of this
