Randomized Nonnegative Matrix Factorization [PDF]

open access: yesPattern Recognition Letters, 2018
Nonnegative matrix factorization (NMF) is a powerful tool for data mining. However, the emergence of `big data' has severely challenged our ability to compute this fundamental decomposition using deterministic algorithms. This paper presents a randomized

Sparse Deep Nonnegative Matrix Factorization [PDF]

open access: yesBig Data Mining and Analytics, 2020
Nonnegative Matrix Factorization (NMF) is a powerful technique to perform dimension reduction and pattern recognition through single-layer data representation learning. However, deep learning networks, with their carefully designed hierarchical structure,

Descent methods for Nonnegative Matrix Factorization [PDF]

open access: yes, 2008
In this paper, we present several descent methods that can be applied to nonnegative matrix factorization and we analyze a recently developped fast block coordinate method called Rank-one Residue Iteration (RRI).

The numerical range of a nonnegative matrix [PDF]

open access: bronzeLinear Algebra and its Applications, 2002
AbstractWe offer an almost self-contained development of Perron–Frobenius type results for the numerical range of an (irreducible) nonnegative matrix, rederiving and completing the previous work of Issos, Nylen and Tam, and Tam and Yang on this topic.

Symmetric nonnegative matrix trifactorization

open access: yesLinear Algebra and its Applications, 2023
The Symmetric Nonnegative Matrix Trifactorization (SN-Trifactorization) is a factorization of an $n \times n$ nonnegative symmetric matrix $A$ of the form $BCB^T$, where $C$ is a $k \times k$ symmetric matrix, and both $B$ and $C$ are required to be nonnegative.

On a Guided Nonnegative Matrix Factorization [PDF]

open access: yesICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
Fully unsupervised topic models have found fantastic success in document clustering and classification. However, these models often suffer from the tendency to learn less-than-meaningful or even redundant topics when the data is biased towards a set of features.
