Method Detail

factorize

public void factorize(SparseMatrix matrix,
             int dimensions)

Description copied from interface: MatrixFactorization

Factorizes the SparseMatrix m. If m is of size MxN, this will generate two matrices: one of size MxnumDimensions and one of size numDimensionsxN. This method must be called before calling dataClasses and classFeatures.

factorize

public void factorize(MatrixFile mfile,
             int dimensions)

Description copied from interface: MatrixFactorization

Factorizes the MatrixFile m. If m is of size MxN, this will generate two matrices: one of size MxnumDimensions and one of size numDimensionsxN. This method must be called before calling dataClasses and classFeatures.

getBuilder

public MatrixBuilder getBuilder()

Returns a MatrixBuilder that is optimized for MatrixFiles that will be processed by this MatrixFactorization algorithm.
