Python Matrix Factorization (PyMF) is a module for several constrained/unconstrained matrix factorization (and related) methods for both sparse and dense matrrices (for a brief introduction to factorization of gigantric matrices have a look at atutorialwe gave at ECML-PKDD 2011). It requires cvxo...
Hoss Belyadi, Alireza Haghighat, in Machine Learning Guide for Oil and Gas Using Python, 2021 Nonnegative matrix factorization (NMF) The main goal in NMF is to decompose a matrix into two matrices. NMF is a matrix factorization technique. As was previously discussed, PCA creates factors that ...
CuMFis a CUDA-based matrix factorization library that optimizes alternate least square (ALS) method to solve very large-scale MF. CuMF uses a set of techniques to maximize the performance on single and multiple GPUs. These techniques include smart access of sparse data leveraging GPU memory hier...
We introduce a new method based on nonnegative matrix factorization, Neural NMF, for detecting latent hierarchical structure in data. Datasets with hierarchical structure arise in a wide variety of fields, such as document classification, image processing, and bioinformatics. Neural NMF recursively appli...
