294 Chapter 9 Supplementary Figure 3. The coefficient of determination (R2) is a measure of goodness of fit, and a standard clustering evaluation metric. We show R2 as a function of the number of clusters, for both the original clustering (green), and for 20 simulated random datasets with no intrinsic clustering (red). The greater coefficient of determination of the EU-NN database indicates intrinsic clusterability. Supplementary Figure 4. Displays the Dunn index for different numbers of clusters, as a standard clustering evaluation metric. The Dunn index is the ratio between the smallest inter-cluster distance and the largest intra-cluster distance. As such, it is high only if all clusters are compact relative to even the smallest separation between clusters.
