Abstract

Random projection is gaining more attention in large scale machine learning. It has been proved to reduce the dimensionality of a set of data whilst approximately preserving the pairwise distance between points by multiplying the original dataset with a chosen matrix. However, projecting data to a lower dimension subspace typically reduces the training accuracy. In this paper, we propose a novel architecture that combines an FPGA-based switch with the ensemble learning method. This architecture enables reducing training time while maintaining high accuracy. Our initial result shows a speedup of 2.12-6.77 times using four different high dimensionality datasets.
