The singular\nvalue decomposition step is optimized through the usage of\nsvds() function in 'RSpectra' package, on a 'dgRMatrix' sparse\nmatrix. Also provides a column-wise error measure in the\nword-topic matrix A, and an algorithm for recovering the\ntopic-document matrix W given A and D based on quadratic\nprogramming. The details about the techniques are explained in\nthe paper \"A new SVD approach to optimal topic estimation\" by\nTracy Ke and Minzhe Wang (2017) .", "License": "MIT + file LICENSE", "LazyData":
