  • Abstract

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.

  • Keywords

Lanczos bidiagonalization, Orthogonal nonnegative matrix factorization, Low-rank approximation, Nonnegative approximation.
