To illustrate these metrics, we plot them on a radar plot for each parameter set. Figure shows an example radar plot for the sample parameter set shown in figure . This example parameter set represents a cluster with a well-defined minimum energy cluster, with optimal values for each of the four identified metrics. The axes of these radar plots are chosen such that better performance on each metric results in a larger total area for the model. In particular, RM SD cluster is plotted on an inverted axis so that a larger value indicates a more compact cluster.
