x
which sampled from a
wolffd@0: Gaussian distribution, and a target variable t
generated by
wolffd@0: computing sin(2*pi*x)
and adding Gaussian noise. A 2-layer
wolffd@0: network with linear outputs is trained by minimizing a sum-of-squares
wolffd@0: error function with isotropic Gaussian regularizer, using the scaled
wolffd@0: conjugate gradient optimizer. The hyperparameters alpha
and
wolffd@0: beta
are re-estimated using the function evidence
. A graph
wolffd@0: is plotted of the original function, the training data, the trained
wolffd@0: network function, and the error bars.
