Extraction of Food Consumption Systems by Nonnegative Matrix Factorization (NMF) for the Assessment of Food Choices

open access: yesBiometrics, 2011
In Western countries where food supply is satisfactory, consumers organize their diets around a large combination of foods. It is the purpose of this article to examine how recent nonnegative matrix factorization (NMF) techniques can be applied to food consumption data to understand these combinations.

Linking Cortical Morphometry in Self-Limited Epilepsy With Centrotemporal Spikes to Cognition, Function, and Molecular Architecture. [PDF]

open access: yesCNS Neurosci Ther
This study provides a novel framework modeling neurodevelopment in self‐limited epilepsy with centrotemporal spikes. We identify eight biologically interpretable brain structural deviation patterns, which are linked to clinical phenotypes and molecular profiles involving cognition and mitochondrial function. This integration elucidates multidimensional

Transductive Nonnegative Matrix Tri-Factorization

open access: yesIEEE Access, 2020
Nonnegative matrix factorization (NMF) decomposes a nonnegative matrix into the product of two lower-rank nonnegative matrices. Since NMF learns parts-based representation, it has been widely used as a feature learning component in many fields.

Image Clustering Algorithm Based on Hypergraph Regularized Nonnegative Tucker Decomposition [PDF]

open access: yesJisuanji gongcheng, 2022
The internal geometry structure of high-dimensional data is ignored when nonnegative tensor decomposition is applied to image clustering.To solve this problem, we propose a Hypergraph regularized Nonnegative Tucker Decomposition(HGNTD) model by adding a ...

NMF-DuNet: Nonnegative Matrix Factorization Inspired Deep Unrolling Networks for Hyperspectral and Multispectral Image Fusion

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The fusion of high-resolution multispectral image (HrMSI) and low-resolution hyperspectral image (LrHSI) has been acknowledged as a promising method for generating a high-resolution hyperspectral image (HrHSI), which is also termed to be an essential part for precise recognition and cataloguing of the underlying materials.
