Webexplore a symmetric variation of NMF that uses A directly as input. When A is properly constructed, the factorization of A will generate a clustering assignment matrix that is nonnegative and well captures the cluster structure inherent in the graph representation. This way, we propose Symmetric NMF (SymNMF) as a new method for graph clustering.
