Non--negative matrix factorization using the \textit{R} package \textsf{nnmf}

arXiv:2607. 20084v1 Announce Type: cross Abstract: Non--negative matrix factorization (NMF) has become an established dimensionality reduction technique for extracting latent structures from non--negative data and has found widespread applications in fields such as bioinformatics, text mining, image analysis, and recommender systems.

On solving symmetric multi-type orthogonal non-negative matrix tri-factorization problem

arXiv:2606. 08291v1 Announce Type: new Abstract: We study the symmetric multi-type orthogonal non-negative matrix tri-factorization problem, where several symmetric non-negative matrices are simultaneously approximated by factors of the form $GS_{i}G^{\top}$, with a shared non-negative and orthogonal factor $G$.

A New Family of Poisson Non-negative Matrix Factorization Methods Using the Shifted Log Link

The paper introduces a new family of Poisson non‑negative matrix factorization (NMF) methods that use a shifted‑log link function, allowing the model to transition from additive to more multiplicative part combinations via a single tuning parameter. An algorithm for maximum‑likelihood fitting and a computationally efficient approximation for large, sparse datasets are presented. Experiments on various real datasets demonstrate that the choice of link function can significantly affect results and may enhance interpretability compared to standard additive Poisson NMF.

Low-rank Distributional Matrix Completion

arXiv:2606. 04176v1 Announce Type: new Abstract: We study a distributional generalization of the matrix completion problem in which each entry of the target matrix is a probability distribution rather than a scalar.
