Gausian Mixture Bayes Classification of photometry
--------------------------------------------------
Figure 9.6

Gaussian mixture Bayes classifier for RR Lyrae stars (see caption of figure 9.3
for details). Here the left panel shows the decision boundary for the
three-component model, and the right panel shows the completeness and
contamination for both a one-component and three-component mixture model. With
all four colors and a three-component model, GMM Bayes achieves a completeness
of 0.686 and a contamination of 0.236.
