  "Description": "Implements many algorithms for statistical learning on\nsparse matrices - matrix factorizations, matrix completion,\nelastic net regressions, factorization machines. Also 'rsparse'\nenhances 'Matrix' package by providing methods for\nmultithreaded <sparse, dense> matrix products and native\nslicing of the sparse matrices in Compressed Sparse Row (CSR)\nformat. List of the algorithms for regression problems: 1)\nElastic Net regression via Follow The Proximally-Regularized\nLeader (FTRL) Stochastic Gradient Descent (SGD), as per McMahan\net al(, <doi:10.1145/2487575.2488200>) 2) Factorization\nMachines via SGD, as per Rendle (2010,\n<doi:10.1109/ICDM.2010.127>) List of algorithms for matrix\nfactorization and matrix completion: 1) Weighted Regularized\nMatrix Factorization (WRMF) via Alternating Least Squares (ALS)\n- paper by Hu, Koren, Volinsky (2008,\n<doi:10.1109/ICDM.2008.22>) 2) Maximum-Margin Matrix\nFactorization via ALS, paper by Rennie, Srebro (2005,\n<doi:10.1145/1102351.1102441>) 3) Fast Truncated Singular Value\nDecomposition (SVD), Soft-Thresholded SVD, Soft-Impute matrix\ncompletion via ALS - paper by Hastie, Mazumder et al. (2014,\n<doi:10.48550/arXiv.1410.2596>) 4) Linear-Flow matrix\nfactorization, from 'Practical linear models for large-scale\none-class collaborative filtering' by Sedhain, Bui, Kawale et\nal (2016, ISBN:978-1-57735-770-4) 5) GlobalVectors (GloVe)\nmatrix factorization via SGD, paper by Pennington, Socher,\nManning (2014, <https://aclanthology.org/D14-1162/>) Package is\nreasonably fast and memory efficient - it allows to work with\nlarge datasets - millions of rows and millions of columns. This\nis particularly useful for practitioners working on recommender\nsystems.",
