or training the hyperparameters). The prediction outputs are
<tt>ymu</tt> and <tt>ys2</tt> for test output mean and covariance, and
<tt>fmu</tt> and <tt>fs2</tt> are the equivalent quenteties for the
corresponding latent variables. Finally, <tt>lp</tt> are the test
output log probabilities.</p>

<p>Instead of exhaustively explaining all the possibilities, we
will give two illustrative examples to give you the idea; one for
regression and one for classification. You can either follow the
example here on this
