Abstract

Generating a low-rank matrix approximation is very important in large-scale machine learning applications. The standard Nyström method is one of the state-of-the-art techniques to generate such an approximation. It has got rapid developments since being applied to Gaussian process regression. Several enhanced Nyström methods such as ensemble Nyström, modified Nyström and SS-Nyström have been proposed. In addition, many sampling methods have been developed. In this paper, we review the Nyström methods for large-scale machine learning. First, we introduce various Nyström methods. Second, we review different sampling methods for the Nyström methods and summarize them from the perspectives of both theoretical analysis and practical performance. Then, we list several typical machine learning applications that utilize the Nyström methods. Finally, we make our conclusions after discussing some open machine learning problems related to Nyström methods.
