Daniel@0: Description Daniel@0:

Daniel@0: [y, extra] = netevfwd(w, net, x, t, x_test) takes a network data Daniel@0: structure Daniel@0: net together with the input x and target t training data Daniel@0: and input test data x_test. Daniel@0: It returns the normal forward propagation through the network y Daniel@0: together with a matrix extra which consists of error bars (variance) Daniel@0: for a regression problem or moderated outputs for a classification problem. Daniel@0: Daniel@0:

The optional argument (and return value) Daniel@0: invhess is the inverse of the network Hessian Daniel@0: computed on the training data inputs and targets. Passing it in avoids Daniel@0: recomputing it, which can be a significant saving for large training sets. Daniel@0: Daniel@0:
