英文摘要：

A distributed learning algorithm is put forward for dissolving the factorization of large-scale nonnegative matrixes.. The factorization of nonnegative matrixes is a hot problem in this field with many effective algorithms. However, the large-scale nonnegative matrixes, there have not been any highly valid algorithms. We combined the distributed concept and the parallel computing with the traditional matrix factorization methods to develop a distributed learning algorithm for complex nonnegative matrix factorization. The simulation experiments show that the proposed algorithm is more efficient and faster than the traditional distributed learning algorithm and matrix factorization methods.
