Categorical encoding of decision variables in orbitofrontal cortex
Fig 7
Cluster results for real data recorded from macaque orbitofrontal cortex limited to the post-juice time window.
(A)-(G) Silhouette plots for the spherical k-means partitions of one example pool (pool 1). Each color corresponds to one cluster. The number of clusters was varied between 2 (A) and 8 (G). (H) Adjusted mutual information cluster similarity between spherical k-means clustering and variable-based centroid clustering as a function of the number of clusters and number of variables over all pools. Corresponding numbers of clusters and numbers of variables are marked in red. (I) Maximum adjusted mutual information for each number of clusters where each bar shows the result of one Jackknife fold.
