Robust Exponential Graph Regularization Non-Negative Matrix Factorization Technology for Feature Extraction

open access: yesMathematics, 2023
Graph regularized non-negative matrix factorization (GNMF) is widely used in feature extraction. In the process of dimensionality reduction, GNMF can retain the internal manifold structure of data by adding a regularizer to non-negative matrix ...

Recommender Systems Clustering Using Bayesian Non Negative Matrix Factorization

open access: yesIEEE Access, 2018
Recommender Systems present a high-level of sparsity in their ratings matrices. The collaborative filtering sparse data makes it difficult to: 1) compare elements using memory-based solutions; 2) obtain precise models using model-based solutions; 3) get ...

Robust capped norm dual hyper-graph regularized non-negative matrix tri-factorization

open access: yesMathematical Biosciences and Engineering, 2023
Non-negative matrix factorization (NMF) has been widely used in machine learning and data mining fields. As an extension of NMF, non-negative matrix tri-factorization (NMTF) provides more degrees of freedom than NMF.

Non-negative Matrix Factorization on Manifold [PDF]

open access: yes2008 Eighth IEEE International Conference on Data Mining, 2008
Recently non-negative matrix factorization (NMF) has received a lot of attentions in information retrieval, computer vision and pattern recognition. NMF aims to find two non-negative matrices whose product can well approximate the original matrix. The sizes of these two matrices are usually smaller than the original matrix. This results in a compressed

Bayesian Non-negative Matrix Factorization [PDF]

open access: yes, 2009
We present a Bayesian treatment of non-negative matrix factorization (NMF), based on a normal likelihood and exponential priors, and derive an efficient Gibbs sampler to approximate the posterior density of the NMF factors. On a chemical brain imaging data set, we show that this improves interpretability by providing uncertainty estimates.
