Class PseudoSequenceDatabase


  • public class PseudoSequenceDatabase
extends java.lang.Object
    Class to make possible the implementation of pseudoprojections already explained in the paper of PrefixSpan Algorithm. By means of this class, we convert a usual sequence in a pseudosequence, where we can point out the different projection points that we have in every database projection. This class is inspired in SPMF PrefixSpan implementation. Copyright Antonio Gomariz Peñalver 2013 This file is part of the SPMF DATA MINING SOFTWARE (http://www.philippe-fournier-viger.com/spmf).
