Class MDSequenceDatabase

java.lang.Object

ca.pfv.spmf.algorithms.sequentialpatterns.fournier2008_seqdim.multidimensionalsequentialpatterns.MDSequenceDatabase

public class MDSequenceDatabase
extends java.lang.Object

Implementation of a "Multi-Dimensional Sequence Database" as used by the SeqDim algorithm (Pinto et al., 2001).

A MD-Sequences database contains a list of md-Sequences, where each MD-Sequence is composed of an MD-Pattern and a Sequence.
