%description
Bayesian Additive Regression Kernels (BARK) provides an implementation for
non-parametric function estimation using Levy Random Field priors for
functions that may be represented as a sum of additive multivariate
kernels.  Kernels are located at every data point as in Support Vector
Machines, however, coefficients may be heavily shrunk to zero under the
Cauchy process prior, or even, set to zero.  The number of active features
is controlled by priors on precision parameters within the kernels,
permitting feature selection. For more details see Ouyang, Z (2008)
