Theorems on Positive Data: On the Uniqueness of NMF [PDF]

open access: yes, 2008
We investigate the conditions for which nonnegative matrix factorization (NMF) is unique and introduce several theorems which can determine whether the decomposition is in fact unique or not.

Graph Sparse Nonnegative Matrix Factorization Algorithm Based on the Inertial Projection Neural Network

open access: yesComplexity, 2018
We present a novel method, called graph sparse nonnegative matrix factorization, for dimensionality reduction. The affinity graph and sparse constraint are further taken into consideration in nonnegative matrix factorization and it is shown that the ...

Monotonous (semi-)nonnegative matrix factorization [PDF]

open access: yesProceedings of the Second ACM IKDD Conference on Data Sciences, 2015
Nonnegative matrix factorization (NMF) factorizes a non-negative matrix into product of two non-negative matrices, namely a signal matrix and a mixing matrix. NMF suffers from the scale and ordering ambiguities. Often, the source signals can be monotonous in nature.
