Nimfa is a Python module that implements many algorithms for nonnegative matrix factorization. Nimfa is distributed under the BSD license. The project was started in 2011 by Marinka Zitnik as a Google Summer of Code project, and since then many volunteers have contributed. See AUTHORS file for ...
Hoss Belyadi, Alireza Haghighat, in Machine Learning Guide for Oil and Gas Using Python, 2021 Nonnegative matrix factorization (NMF) The main goal in NMF is to decompose a matrix into two matrices. NMF is a matrix factorization technique. As was previously discussed, PCA creates factors that ...

NMF (Nonnegative Matrix Factorization)In this study, we deal with the neutron flux monitoring inside the TRIGA MARK II reactor as one of the nonnegative matrix factorization problems. The fact that these methods of separating blind sources does not require any assumptions on the way the signal ...
Nonnegative matrix factorization (NMF) has been introduced as an efficient way to reduce the complexity of data compression and its capability of extracting highly interpretable parts from data sets, and it has also been applied to various fields, such as recommendations, image analysis, and text ...
We introduce a new method based on nonnegative matrix factorization, Neural NMF, for detecting latent hierarchical structure in data. Datasets with hierarchical structure arise in a wide variety of fields, such as document classification, image processing, and bioinformatics. Neural NMF recursively appli...

Recently, nonnegative matrix factorization (NMF) has been widely adopted for community detection, because of its better interpretability. However, the existing NMF-based methods have the following three problems: 1. they directly transform the original network into community membership space, so it is...
