Detailed Description

Implementation of random fourier feature map for feature processing.

Applies sqrt(2 / output_dims) * cos(wx+b), where:
    output_dims is the output feature dimensions, and
    wx + b applies FC using randomized, fixed weight and bias parameters

For more information, see the original paper:

    output_dims -- output feature dimensions
    sigma -- bandwidth for the Gaussian kernel estimator
    w_init -- initalization options for weight parameter
    b_init -- initalization options for bias parameter
