Apply Collaborative Filtering to the provided dataset using NMF method.

Parameters
dataData matrix: dense matrix (coordinate lists) or sparse matrix(cleaned).
cleanedDataitem user table in form of sparse matrix.
rankRank parameter for matrix factorization.
wFirst matrix formed after decomposition.
hSecond matrix formed after decomposition.
maxIterationsMaximum number of iterations.
minResidueResidue required to terminate.
mitWhether to terminate only when maxIterations is reached.
