Daniel@0 26 Description
Daniel@0 27 </h2>
Daniel@0 28 <CODE>[y, extra] = netevfwd(w, net, x, t, x_test)</CODE> takes a network data
Daniel@0 29 structure
Daniel@0 30 <CODE>net</CODE> together with the input <CODE>x</CODE> and target <CODE>t</CODE> training data
Daniel@0 31 and input test data <CODE>x_test</CODE>.
Daniel@0 32 It returns the normal forward propagation through the network <CODE>y</CODE>
Daniel@0 33 together with a matrix <CODE>extra</CODE> which consists of error bars (variance)
Daniel@0 34 for a regression problem or moderated outputs for a classification problem.
Daniel@0 35
Daniel@0 36 <p>The optional argument (and return value)
Daniel@0 37 <CODE>invhess</CODE> is the inverse of the network Hessian
Daniel@0 38 computed on the training data inputs and targets. Passing it in avoids
Daniel@0 39 recomputing it, which can be a significant saving for large training sets.
