Reverse annealing for nonnegative/binary matrix factorization.

open access: yesPLoS ONE, 2021
It was recently shown that quantum annealing can be used as an effective, fast subroutine in certain types of matrix factorization algorithms. The quantum annealing algorithm performed best for quick, approximate answers, but performance rapidly ...

Optimization of identifiability for efficient community detection

open access: yesNew Journal of Physics, 2020
Many physical and social systems are best described by networks. And the structural properties of these networks often critically determine the properties and function of the resulting mathematical models.

Deep Nonnegative Dictionary Factorization for Hyperspectral Unmixing

open access: yesRemote Sensing, 2020
As a powerful blind source separation tool, Nonnegative Matrix Factorization (NMF) with effective regularizations has shown significant superiority in spectral unmixing of hyperspectral remote sensing images (HSIs) owing to its good physical ...

Latent Multi-View Semi-Nonnegative Matrix Factorization with Block Diagonal Constraint

open access: yesAxioms, 2022
Multi-view clustering algorithms based on matrix factorization have gained enormous development in recent years. Although these algorithms have gained impressive results, they typically neglect the spatial structures that the latent data representation ...

A multilevel approach for nonnegative matrix factorization [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2012
Nonnegative Matrix Factorization (NMF) is the problem of approximating a nonnegative matrix with the product of two low-rank nonnegative matrices and has been shown to be particularly useful in many applications, e.g., in text mining, image processing, computational biology, etc. In this paper, we explain how algorithms for NMF can be embedded into the

Fairer non-negative matrix factorization

open access: yesFrontiers in Big Data
There has been a recent critical need to study fairness and bias in machine learning (ML) algorithms. Since there is clearly no one-size-fits-all solution to fairness, ML methods should be developed alongside bias mitigation strategies that are practical

Multi-Component Nonnegative Matrix Factorization [PDF]

open access: yesProceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence, 2017
Real data are usually complex and contain various components. For example, face images have expressions and genders. Each component mainly reflects one aspect of data and provides information others do not have. Therefore, exploring the semantic information of multiple components as well as the diversity among them is of great benefit to understand ...
