GeneralizedSequentialPatterns
Package
weka.associations
Synopsis
Class implementing a GSP algorithm for discovering sequential patterns in a sequential data set.
The attribute identifying the distinct data sequences contained in the set can be determined by the respective option. Furthermore, the set of output results can be restricted by specifying one or more attributes that have to be contained in each element/itemset of a sequence.

Available in Weka 3.6.x - 3.7.1. Available via the package management system for Weka >= 3.7.2 (generalizedSequentialPatterns).
Options
The table below describes the options available for GeneralizedSequentialPatterns.
Option |
Description |
|---|---|
dataSeqID |
The attribute number representing the data sequence ID. |
debug |
If set to true, algorithm may output additional info to the console. |
filterAttributes |
The attribute numbers (eg "0, 1") used for result filtering; only sequences containing the specified attributes in each of their elements/itemsets will be output; -1 prints all. |
minSupport |
Minimum support threshold. |
