edu.ucla.sspace.matrix.CorrelationTransform

All Implemented Interfaces:

Transform

public class CorrelationTransform
extends BaseTransform

Transforms a matrix using row correlation weighting. The input matrix is assumed to be formatted as rows representing terms and columns representing co-occuring terms. Each matrix cell indicates the number of times the row's word occurs the other term. See the following paper for details and analysis:
