h = hbayes(net, hdata) [h, hdata] = hbayes(net, hdata)
h = hbayes(net, hdata)
takes a network data structure net
together
the data contribution to the Hessian
for a set of inputs and targets.
It returns the regularised Hessian using any zero mean Gaussian priors
on the weights defined in
net
. In addition, if a mask
is defined in net
, then
the entries in h
that correspond to weights with a 0 in the
mask are removed.
[h, hdata] = hbayes(net, hdata)
additionally returns the
data component of the Hessian.
