A Unified Convergence Analysis of the Multiplicative Update Algorithm for Regularized Nonnegative Matrix Factorization
Renbo Zhao, Vincent Y. F. Tan
The multiplicative update (MU) algorithm has been extensively used to estimate the basis and coefficient matrices in nonnegative matrix factorization (NMF) problems under a wide ra…
Online Nonnegative Matrix Factorization with General Divergences
Renbo Zhao, Vincent Y. F. Tan, Huan Xu
We develop a unified and systematic framework for performing online nonnegative matrix factorization under a wide variety of important divergences. The online nature of our algorit…
Online Nonnegative Matrix Factorization with Outliers
Renbo Zhao, Vincent Y. F. Tan
We propose a unified and systematic framework for performing online nonnegative matrix factorization in the presence of outliers. Our framework is particularly suited to large-scal…
Adversarial Top- Ranking
Changho Suh, Vincent Y. F. Tan, Renbo Zhao
We study the top- ranking problem where the goal is to recover the set of top- ranked items out of a large collection of items based on partially revealed preferences. We con…
