Class SVDBuilder

java.lang.Object
  transcript.algorithms.modelbased.svd.SVDBuilder

public class SVDBuilder
extends java.lang.Object

This class uses the colt library's SingularValueDecomposition class to create and serialize an SVD object for the transcript data. The program takes 4 arguments: 1) The number of courses. 2) The number of students. 3) The file containing the TranscriptMemReader. 4) Fhe file to write the SVD to. The program requires that the number of movies and number of users be explicitely input to allow for both 0 and 1 indexed datasets.
