There are ways to get the most "typical" (I think there is a better term for that) sample of a cluster, which should usually lie in the center of the cluster. AFAIK that's the traditional way to achieve what you are trying to do.
- alexcnwy 9y agoTry compute the median point across all members of the cluster then compute the cosine similarity between each point in the cluster and the median of that cluster and use the most similar as your label point.
- vanderZwan 9y agoThe clusters on our tSNE plots tend to be stretched out, have concave bits and en up intertwined - we'd have the exact same problem outlined in this article. In fact, that was the whole reason we started discussing it, since I initially proposed just doing what you suggested
- hobofan 9y agoGood to know! I must've been lucky, since most tSNE plots I've worked with were pretty tame in that respect.
