## Abstract (arXiv)

We prove that, under low noise assumptions, the support vector machine with Nll m random features (RFSVM) can achieve the learning rate faster than O(1/√m) on a training set with m samples when an optimized feature map is used. Our work extends the previous fast rate analysis of random features method from least square loss to 0-1 loss. We also show that the reweighted feature selection method, which approximates the optimized feature map, helps improve the performance of RFSVM in experiments on a synthetic data set.
