Feature Weighted Non-Negative Matrix Factorization [PDF]

open access: yesIEEE Transactions on Cybernetics, 2023
Non-negative Matrix Factorization (NMF) is one of the most popular techniques for data representation and clustering, and has been widely used in machine learning and data analysis. NMF concentrates the features of each sample into a vector, and approximates it by the linear combination of basis vectors, such that the low-dimensional representations ...

Non-negative Matrix Factorization for Dimensionality Reduction [PDF]

open access: yesITM Web of Conferences, 2022
—What matrix factorization methods do is reduce the dimensionality of the data without losing any important information. In this work, we present the Non-negative Matrix Factorization (NMF) method, focusing on its advantages concerning other methods of ...

Truncated Cauchy Non-Negative Matrix Factorization [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2019
Non-negative matrix factorization (NMF) minimizes the Euclidean distance between the data matrix and its low rank approximation, and it fails when applied to corrupted data because the loss function is sensitive to outliers. In this paper, we propose a Truncated CauchyNMF loss that handle outliers by truncating large errors, and develop a Truncated ...

Guided Semi-Supervised Non-Negative Matrix Factorization

open access: yesAlgorithms, 2022
Classification and topic modeling are popular techniques in machine learning that extract information from large-scale datasets. By incorporating a priori information such as labels or important features, methods have been developed to perform ...

Probabilistic Non-Negative Matrix Factorization with Binary Components

open access: yesMathematics, 2021
Non-negative matrix factorization is used to find a basic matrix and a weight matrix to approximate the non-negative matrix. It has proven to be a powerful low-rank decomposition technique for non-negative multivariate data.

Rank selection for non‐negative matrix factorization

open access: yesStatistics in Medicine, 2023
Non‐Negative Matrix Factorization (NMF) is a widely used dimension reduction method that factorizes a non‐negative data matrix into two lower dimensional non‐negative matrices: one is the basis or feature matrix which consists of the variables and the other is the coefficients matrix which is the projections of data points to the new basis.

Shifted Non-Negative Matrix Factorization [PDF]

open access: yes2007 IEEE Workshop on Machine Learning for Signal Processing, 2007
Non-negative matrix factorization (NMF) has become a widely used blind source separation technique due to its part based representation and ease of interpretability. We currently extend the NMF model to allow for delays between sources and sensors. This is a natural extension for spectrometry data where a shift in onset of frequency profile can be ...
