Abstract: Dear Editor, This letter presents a novel symmetry and nonnegativity-constrained matrix factorization (SNCMF)-based community detection model on undirected networks such as a social network.

(NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of single-qubit quantum neural network technology for ...

In the least squares method for simultaneous adjustment of several parameters, the coefficients of the normal equations are the elements of a symmetric positive-definite matrix. In order to solve the ...

Recently, in order to find the principal moments of inertia of a large number of rigid bodies, it was necessary to compute the eigenvalues of many real, symmetric 3 × 3 matrices. The available ...

Several fields of mathematics have developed in total isolation, using their own 'undecipherable' coded languages. Mathematicians now present 'big algebras,' a two-way mathematical 'dictionary' ...

A 3D-printed decuplet crystal, skeleton, and nerves of a big algebra designed by Daniel Bedats. Printed with the Stratasys J750 3D printer at ISTA’s Miba Machine Shop. Symmetry is not just a question ...

Hi, can ELPA only get half of the symmetric matrix and compute the eigenvalue and eigenvector? Just like ScaLAPACK pdsyevd? There is a symmetric matrix that will be transformed before computing its ...

In this paper, we explore the inverse spectral problem for a kind of pseudo-symmetric matrix A(ε,c,s) that corresponds to a graph of a banana tree when all ε=1. The problem of reconstructing ...

Note: this is an experiment with UMFPACK_STRATEGY_UNSYMMETRIC, and may not be a bug, really. Tested on Ubuntu 22.04 and Ubuntu 23.04 with UMFPACK V5.7 (Oct 20, 2019) and UMFPACK V6.2 (Sept 18, 2023).
