It has become a common method for generating topic models of text data because it is known to produce good results, despite its relative simplicity of implementation and ease of computation. In this paper we brieﬂy describe the motivation behind this type of data representation and its relation to standard sparse coding and non-negative matrix factorization. In addition to non-negativity, the low-rank and sparse properties of the factorization results of NMF are also appealing to the researchers. Hoyer, P.O. 04/15/2018 ∙ by Jonghye Woo, et al.
