An Effective Initialization for Orthogonal Nonnegative Matrix Factorization
Xuansheng Wang, Xiaoyao Xie null, Linzhang Lu · Journal of Computational Mathematics · 2012
The orthogonal nonnegative matrix factorization (ONMF) has many applications in a variety of areas such as data mining, information processing and pattern recognition.In this paper, we propose a novel initialization method for the ONMF based on the Lanczos bidiagonalization and the nonnegative approximation of rank one matrix.Numerical experiments are given to show that our initialization strategy is effective and efficient.
