Web1 de mai. de 2009 · In our framework, the user-item matrix X is first approximated by using orthogonal nonnegative matrix tri-factorization, so that the co-clustering of both users and items can be achieved. Suppose that X is factorized as USV T ( U T U = I, V T V = I), where U ∈ R + p × k, S ∈ R + k × l, and V ∈ R + n × l.
