Figure 8.

Full polythetic classification. Unsupervised clusterings of 68 neocortical interneurons based on laminar location and morphological, electrophysiological, and molecular properties. Comparison between the silhouette width for the full polythetic K-means clustering and the average silhouette width of randomized databases. Absolute and relative quality losses are shown for the cases of scrambling limited to morphological properties, to electrophysiological properties, or to molecular properties. Error bars of the scrambled silhouette width are evaluated by SD over 1000 independent randomizations.
