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

I was diving deeper into community/trend detection on graphs, so @howard.fm 's post about AI on bsky was a good opportunity to test some things:
I read 5k profiles and created this interactive chart to find AI communities, using hierarchical leiden + laplasian centrality: flowscope.ai/bsky_bubbles
