| Abstract: | The clustering aspect of various nonnegative matrix factorization (NMF) objectives which include standard NMF, orthogonal NMF, sparse NMF, Semi-NMF, and Convex NMF have been reported in many papers. However, there is still no comprehensive study that provides a theoretical explanation on this aspect yet. In this work, we provide such explanation by showing that at the respective stationary points in nonnegative orthant of the feasible regions, which are the solutions pursued by NMF algorithms, the NMF objectives are equivalent to the graph clustering objective, therefore the clustering aspect of NMF has a solid justification. |
