The NMF\nprocedure decomposes a matrix X into a product C * D. Given\nconditions such that the matrix C is non-negative and has\nsufficiently spread columns, then volume minimization of a\nmatrix D delivers a correct and unique, up to a scale and\npermutation, solution (C, D). This package provides both an\nimplementation of volume-regularized NMF and \"anchor-free\" NMF,\nwhereby the standard NMF problem is reformulated in the\ncovariance domain. This algorithm was applied in Vladimir B.\nSeplyarskiy Ruslan A. Soldatov, et al. \"Population sequencing\ndata reveal a compendium of mutational processes in the human\ngerm line\". Science, 12 Aug 2021.\n. This package interacts with data\navailable through the 'simulatedNMF' package, which is\navailable in a 'drat' repository. To access this data package,\nsee the instructions at\n. The size of the\n'simulatedNMF' package is approximately 8 MB.", "License": "GPL-3", "Encoding": "UTF-8", "RoxygenNote": "7.1.2", "URL": "https://github.com/kharchenkolab/vrnmf", "BugReports":
