hbayes

Purpose

Evaluate Hessian of Bayesian error function for network.

Synopsis

h = hbayes(net, hdata)
[h, hdata] = hbayes(net, hdata)

Description

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.
