K-neighbors Classification of photometry
----------------------------------------
Figure 9.7

K-nearest-neighbor classification for RR Lyrae stars (see caption of figure 9.3
for details). Here the left panel shows the decision boundary for the model
based on K = 10 neighbors, and the right panel shows the completeness and
contamination for both K = 1 and K = 10. With all four colors and K = 10,
K-neighbors classification achieves a completeness of 0.533 and a contamination
of 0.240.
