Abstract

Data-intensive applications are becoming important in many science and engineering fields, because of the high rates in which data are being generated and the numerous opportunities offered by the sheer amount of these data. Large-scale datasets, however, are challenging to process using many of the current machine learning algorithms due to their high time and space complexities. In this paper, we propose a novel approximation algorithm that enables kernel-based machine learning algorithms to efficiently process very large-scale datasets. While important in many applications, current kernel-based algorithms suffer from a scalability problem as they require computing a kernel matrix which takes O(N2) in time and space to compute and store. The proposed algorithm yields substantial reduction in computation and memory overhead required to compute the kernel matrix, and it does not significantly impact …
