%description
Provides various basis expansions for flexible regression modeling,
including random Fourier features (Rahimi & Recht, 2007)
<https://proceedings.neurips.cc/paper_files/paper/2007/file/013a006f03dbc5392effeb8f18fda755-Paper.pdf>,
exact kernel / Gaussian process feature maps, Bayesian Additive Regression
Trees (BART) (Chipman et al., 2010) <doi:10.1214/09-AOAS285> prior
features, and a helpful interface for n-way interactions. The provided
functions may be used within any modeling formula, allowing the use of
kernel methods and other basis expansions in modeling functions that do
not otherwise support them. Along with the basis expansions, a number of
kernel functions are also provided, which support kernel arithmetic to
form new kernels. Basic ridge regression functionality is included as
well.
