Fairer non-negative matrix factorization. [PDF]

open access: yesFront 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

Collaborative filtering based on nonnegative/binary matrix factorization. [PDF]

open access: yesFront Big Data
Collaborative filtering generates recommendations by exploiting user-item similarities based on rating data, which often contains numerous unrated items.

Deep maximum margin matrix factorization. [PDF]

open access: yesSci Rep
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 ...

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.

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 ...

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

Localization of Matrix Factorizations [PDF]

open access: yesFoundations of Computational Mathematics, 2014
Matrices with off-diagonal decay appear in a variety of fields in mathematics and in numerous applications, such as signal processing, statistics, communications engineering, condensed matter physics, and quantum chemistry. Numerical algorithms dealing with such matrices often take advantage (implicitly or explicitly) of the empirical observation that ...

Boolean Matrix Factorization via Nonnegative Auxiliary Optimization

open access: yesIEEE Access, 2021
A novel approach to Boolean matrix factorization (BMF) is presented. Instead of solving the BMF problem directly, this approach solves a nonnegative optimization problem with an additional constraint over an auxiliary matrix whose Boolean structure is ...
