Given a matrix factorization object \(A = B C\), this function returns for each document the index of the inner dimension which has the maximal coordinate. Thus, it converts the fuzzy clustering found in the columns of the \(C\) matrix into a hard clustering by returning the position with the maximal coordinate value.
getMatrixFactorizationLabels(prismaMF)
a matrix factorization object.
vector containing the label assignment for each document.
