edata = gperr(net, x, t) [e, edata, eprior] = gperr(net, x, t)
e = gperr(net, x, t)
takes a Gaussian Process data structure net
together
with a matrix x
of input vectors and a matrix t
of target
vectors, and evaluates the error function e
. Each row
of x
corresponds to one input vector and each row of t
corresponds to one target vector.
[e, edata, eprior] = gperr(net, x, t)
additionally returns the
data and hyperprior components of the error, assuming a Gaussian
prior on the weights with mean and variance parameters prmean
and
prvariance
taken from the network data structure net
.
