QMC Feature Maps

Codes for quasi-Monte Carlo feature maps for Gaussian kernels in MATLAB.

About

Given any pair of points x and y, compute a feature map z(x) and z(y) such that k(x,y) is approximated by the inner product between z(x) and z(y) where in this case k is the Gaussian kernel.

Usage

See qmc_faeture_maps_complex.m for usage. See demo.m for a simple example.
