<p>We specify a Gaussian process model as follows: a constant mean
function, with initial parameter set to 0, a squared exponential with
automatic relevance determination (ARD) covariance function <a

one characteristic length-scale parameter for each dimension of the
input space, and a signal magnitude parameter, for a total of 3
parameters (as the input dimension is <tt>D=
