The values in <CODE>x</CODE> are chosen in two separated clusters and the +target data is generated by computing <CODE>sin(2*pi*x)</CODE> and adding Gaussian +noise. Two Gaussian Processes, each with different covariance functions +are trained by optimising the hyperparameters +using the scaled conjugate gradient algorithm. The final predictions are +plotted together with 2 standard deviation error bars. + +<p><h2> +See Also +</h2> +<CODE><a href="gp.htm">gp</a></CODE>, <CODE><a href="gperr.htm">gperr</a></CODE>, <CODE><a href="gpfwd.htm">gpfwd</a></CODE>, <CODE><a href="gpgrad.htm">gpgrad</a></CODE>, <CODE><a href="gpinit.htm">gpinit</a></CODE>, <CODE><a href="scg.htm">scg</a></CODE><hr> +<b>Pages:</b> +<a href="index.htm">Index</a> +<hr> +<p>Copyright (c) Ian T Nabney (1996-9) + + +</body> +</html> \ No newline at end of file
