In this paper we consider estimating the rank of an unknown symmetric matrix based on a symmetric, asymptotically normal estimator of the matrix. The related positive definite limit covariance matrix ...

Add a description, image, and links to the symmetric-matrix topic page so that developers can more easily learn about it ...

To address the above issues, this article proposes an orthogonal symmetric nonnegative matrix factorization (SNMF) with low-rank tensor representation (OSNMFTR) for multilayer networks community ...

Clean adjacency matrices are then used to perform orthogonal symmetric non-negative matrix factorization, extracting latent representations of the multi-layer networks. Moreover, the nuclear norm is ...
