Non-negative matrix factorization (NMF, 음수 미포함 행렬 분해), also non-negative matrix approximation is a group of algorithms in Multivariate analysis and Linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. (https://en.wikipedia.org/wiki/Non-negative_matrix_factorization)

One of the Matrix decomposition methods.

음수를 포함하지 않은 행렬 V를 음수를 포함하지 않은 행렬 W와 H로 분해하는 알고리즘.
