On the equivalence between Non-negative Matrix Factorization and Probabilistic Latent Semantic Indexing

Ding, Chris; Li, Tao; Peng, Wei - In: Computational Statistics & Data Analysis 52 (2008) 8, pp. 3913-3927

Non-negative Matrix Factorization (NMF) and Probabilistic Latent Semantic Indexing (PLSI) have been successfully applied to document clustering recently. In this paper, we show that PLSI and NMF (with the I-divergence objective function) optimize the same objective function, although PLSI and...
