Class MDSequence

java.lang.Object

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

public class MDSequence
extends java.lang.Object

Implementation of a "MultiDimensional-Sequence" used by the SeqDim algorithm (Pinto et al., 2001).

An MD-Sequence is associated to a MD-Database.

An MD-Sequence has two parts: an mdpattern (the values for each dimension) and a sequence.
