Method Detail

factorizationFactory

public TermDocumentMatrixReducerDescriptor.AttributeBuilder factorizationFactory(IMatrixFactorizationFactory value)

Factorization method. The method to be used to factorize the term-document matrix and create base vectors that will give rise to cluster labels.

factorizationFactory

public TermDocumentMatrixReducerDescriptor.AttributeBuilder factorizationFactory(Class<?> clazz)

Factorization method. The method to be used to factorize the term-document matrix and create base vectors that will give rise to cluster labels. A class that extends org.carrot2.matrix.factorization.IMatrixFactorizationFactory or appropriate IObjectFactory.

factorizationQuality

public TermDocumentMatrixReducerDescriptor.AttributeBuilder factorizationQuality(IterationNumberGuesser.FactorizationQuality value)

Factorization quality. The number of iterations of matrix factorization to perform. The higher the required quality, the more time-consuming clustering.
