wolffd@0: Description wolffd@0:

wolffd@0: wolffd@0: e = mdnerr(net, x, t) takes a mixture density network data wolffd@0: structure net, a matrix x of input vectors and a matrix wolffd@0: t of target vectors, and evaluates the error function wolffd@0: e. The error function is the negative log likelihood of the wolffd@0: target data under the conditional density given by the mixture model wolffd@0: parameterised by the MLP. Each row of x corresponds to one wolffd@0: input vector and each row of t corresponds to one target vector. wolffd@0: wolffd@0:
