and by "head" I mean "the highest laplasian centrality approximation score"
so @karpathy.bsky.social is the head of general AI cluster and @chrisoffner3d.bsky.social is of compvision, @zouharvi.bsky.social is of nlp etc

Some examples: @rpmumme.bsky.social is the head of compbio cluster, with @alexr.bsky.social a head of subcluster of compbio&genomics
