Novel Algorithms Based on Majorization Minimization for Nonnegative Matrix Factorization
IEEE Access, 2019 Matrix decomposition is ubiquitous and has applications in various fields like speech processing, data mining and image processing to name a few. Under matrix decomposition, nonnegative matrix factorization is used to decompose a nonnegative matrix into ...

Factorization of generalized γ-generating matrices [PDF]
Journal of Mathematical Sciences, 2018 The class of \(\gamma\)-generating matrices and its subclasses of regular and singular \(\gamma\)-generating matrices were introduced in [\textit{D. Z. Arov}, J. Sov. Math. 52, No. 6, 3487--3491 (1990; Zbl 0718.41004); translation from Teor. Funkts., Funkts. Anal. Prilozh.

Using Dynamic Multi-Task Non-Negative Matrix Factorization to Detect the Evolution of User Preferences in Collaborative Filtering. [PDF]
PLoS ONE, 2015 Predicting what items will be selected by a target user in the future is an important function for recommendation systems. Matrix factorization techniques have been shown to achieve good performance on temporal rating-type data, but little is known about

Pentadiagonal Companion Matrices
Special Matrices, 2016 The class of sparse companion matrices was recently characterized in terms of unit Hessenberg matrices. We determine which sparse companion matrices have the lowest bandwidth, that is, we characterize which sparse companion matrices are permutationally ...

Factorizations of Matrices over Projective-free Rings [PDF]
Algebra Colloquium, 2016 An element of a ring R is called strongly J#-clean provided that it can be written as the sum of an idempotent and an element in J#(R) that commute. In this paper, we characterize the strong J#-cleanness of matrices over projective-free rings. This extends many known results on strongly clean matrices over commutative local rings.

Factorization of Delannoy matrices
Elemente der Mathematik, 2021 Summary: The Delannoy matrices are factorized with Pascal matrices, which easily results in the Cholesky decomposition and the inverse of such matrices. The determinants of Delannoy matrices are connected with triangular numbers. Finally, a factorization of Delannoy matrices with Hypercube matrices and Pascal matrices is given.

Elementary triangular matrices and inverses of k-Hessenberg and triangular matrices
Special Matrices, 2015 We use elementary triangular matrices to obtain some factorization, multiplication, and inversion properties of triangular matrices. We also obtain explicit expressions for the inverses of strict k-Hessenberg matrices and banded matrices. Our results can

Differential expansion for antiparallel triple pretzels: the way the factorization is deformed
European Physical Journal C: Particles and Fields, 2022 For a peculiar family of double braid knots there is a remarkable factorization formula for the coefficients of the differential (cyclotomic) expansion (DE), which nowadays is widely used to construct the exclusive Racah matrices S and $${\bar{S}}$$ S ...

Frontiers in Cell and Developmental Biology, 2022 Calculating and predicting drug-target interactions (DTIs) is a crucial step in the field of novel drug discovery. Nowadays, many models have improved the prediction performance of DTIs by fusing heterogeneous information, such as drug chemical structure
