Fairer non-negative matrix factorization [PDF]

open access: yesFrontiers in Big Data
There has been a recent critical need to study fairness and bias in machine learning (ML) algorithms. Since there is clearly no one-size-fits-all solution to fairness, ML methods should be developed alongside bias mitigation strategies that are practical

Deep maximum margin matrix factorization [PDF]

open access: yesScientific Reports
Collaborative filtering (CF) over ordinal feedback is naturally organized as a problem of matrix completion, where the input consists of a partially observed user-item interaction matrix. Maximum Margin Matrix Factorization (MMMF) has achieved widespread

Some properties of various types of matrix factorization [PDF]

open access: yesITM Web of Conferences, 2021
Matrix factorizations or matrix decompositions are methods that represent a matrix as a product of two or more matrices. There are various types of matrix factorizations such as LU factorization, Cholesky factorization, singular value decomposition etc ...

Deviance matrix factorization

open access: yesElectronic Journal of Statistics, 2023
We investigate a general matrix factorization for deviance-based data losses, extending the ubiquitous singular value decomposition beyond squared error loss. While similar approaches have been explored before, our method leverages classical statistical methodology from generalized linear models (GLMs) and provides an efficient algorithm that is ...

Neural Metric Factorization for Recommendation

open access: yesMathematics, 2022
All current recommendation algorithms, when modeling user–item interactions, basically use dot product. This dot product calculation is derived from matrix factorization.

Matrix Factorization Techniques in Machine Learning, Signal Processing, and Statistics

open access: yesMathematics, 2023
Compressed sensing is an alternative to Shannon/Nyquist sampling for acquiring sparse or compressible signals. Sparse coding represents a signal as a sparse linear combination of atoms, which are elementary signals derived from a predefined dictionary ...

MatMat: Matrix Factorization by Matrix Fitting [PDF]

open access: yes2021 IEEE 4th International Conference on Information Systems and Computer Aided Education (ICISCAE), 2021
Matrix factorization is a widely adopted recommender system technique that fits scalar rating values by dot products of user feature vectors and item feature vectors. However, the formulation of matrix factorization as a scalar fitting problem is not friendly to side information incorporation or multi-task learning. In this paper, we replace the scalar

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 ...
