e = mlperr(net, x, t)
e = mlperr(net, x, t)
takes a network data structure net
together
with a matrix x
of input vectors and a matrix t
of target
vectors, and evaluates the error function e
. The choice of error
function corresponds to the output unit activation function. Each row
of x
corresponds to one input vector and each row of t
corresponds to one target vector.
[e, edata, eprior] = mlperr(net, x, t)
additionally returns the
data and prior components of the error, assuming a zero mean Gaussian
prior on the weights with inverse variance parameters alpha
and
beta
taken from the network data structure net
.
