Normalized hodge laplacian matrix and its spectrum
2023Let ? be a simplicial complex, ?[ Subscript ?] ∶ ?[ Subscript ?] → ?[ Subscript ?−1] a boundary map on ? and ?[ Subscript ?] a matrix representation of ?[ Subscript ?]. A Hodge ?-Laplacian matrix on simplicial complexes is defined by ?[ Subscript ?]

Non-negative matrix factorization for images with Laplacian noise
APCCAS 2008 - 2008 IEEE Asia Pacific Conference on Circuits and Systems, 2008This paper is concerned with the design of a non-negative matrix factorization algorithm for image analysis. This can be used in the context of blind source separation, where each observed image is a linear combination of a few basis functions, and that both the coefficients for the linear combination and the bases are unknown.

Hermitian skew Laplacian matrix of oriented graphs
Discrete Mathematics, Algorithms and ApplicationsLet [Formula: see text] be a simple graph of order [Formula: see text] having [Formula: see text] edges and let [Formula: see text] be an orientation of [Formula: see text]. The hermitian skew Laplacian matrix [Formula: see text] of [Formula: see text] is defined as [Formula: see text], where [Formula: see text] is the imaginary unit, [Formula: see ...
