Categorical encoding of decision variables in orbitofrontal cortex
Fig 6
Comparison of different cluster similarity measures for spherical k-means partitions on synthetic data.
Data were either categorical (top row) or non-categorical (bottom row) and simulated like in Figs 3 and 4. The similarity measure was either mutual information (A, D), normalized mutual information (B, E) or adjusted mutual information (C, F). The gray scale indicates the strength of similarity for given number of clusters and number of variables. Corresponding numbers of clusters and numbers of variables are marked in red.
