Abstract:

Transformed matrix based nonnegative matrix factorization method is proposed. It shows that the new method, with similar complexity to the known schemes, is efficient in reducing the iteration number for nonnegative matrix factorization.

Key words: nonnegative matrix factorization, alternating nonnegative least squares method, matrix transformation
