Optical Implementation Of Matrix-Vector And Matrix-Matrix Multiplication

Journal of Optics, 1992
From the viewpoint of information processing, the main advantage of an optical processor is its ability to operate in a highly parallel way. One of the most important applications of an optical processor, where its parallelism is efficiently used, is considered to be linear transformation because it involves many multiplications and additions in ...

Nonnegative matrix factorization with matrix exponentiation

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
Nonnegative matrix factorization (NMF) has been successfully applied to different domains as a technique able to find part-based linear representations for nonnegative data. However, when extra constraints are incorporated into NMF, simple gradient descent optimization can be inefficient for high-dimensional problems, due to the overhead to enforce the

Practical criteria for positive-definite matrix, M-matrix and Hurwitz matrix

Applied Mathematics and Computation, 2007
A new simple criterion is presented to verify if a matrix is positive definite, an \(M\)-matrix, or a Hurwitz matrix. It is based on the Gauss row elimination using inner and sign-preserving row operations. The computation of only one determinant is necessary.
