On Rationality of Nonnegative Matrix Factorization [PDF]

open access: yesProceedings of the Twenty-Eighth Annual ACM-SIAM Symposium on Discrete Algorithms, 2017
Nonnegative matrix factorization (NMF) is the problem of decomposing a given nonnegative n × m matrix M into a product of a nonnegative n × d matrix W and a nonnegative d × m matrix H. NMF has a wide variety of applications, including bioinformatics, chemometrics, communication complexity, machine learning, polyhedral combinatorics, among many others ...

A Fast Gradient Method for Nonnegative Sparse Regression with Self Dictionary

open access: yes, 2017
A nonnegative matrix factorization (NMF) can be computed efficiently under the separability assumption, which asserts that all the columns of the given input data matrix belong to the cone generated by a (small) subset of them.

Accelerating Nonnegative Matrix Factorization Algorithms using Extrapolation

open access: yes, 2018
In this paper, we propose a general framework to accelerate significantly the algorithms for nonnegative matrix factorization (NMF). This framework is inspired from the extrapolation scheme used to accelerate gradient methods in convex optimization and ...

Multimode Process Monitoring Method Based on Multiblock Projection Nonnegative Matrix Factorization

open access: yesAdvances in Mathematical Physics, 2020
A multimode process monitoring method based on multiblock projection nonnegative matrix factorization (MPNMF) is proposed for traditional process monitoring methods which often adopt global model of data and ignore local information of data. Firstly, the

Ranking Preserving Nonnegative Matrix Factorization [PDF]

open access: yes, 2018
Nonnegative matrix factorization (NMF), a wellknown technique to find parts-based representations of nonnegative data, has been widely studied. In reality, ordinal relations often exist among data, such as data i is more related to j than to q. Such
