I assume that only the used data types have to be adapted and then it can be more or less directly moved to flink-ml. > The kMeans++ [1] and the kMeans|| [2] algorithm constitute a better implementation because the improve the initial seeding phase to achieve near optimal clustering. It might be worthwhile to implement kMeans||. > Resources: > [1] http://ilpubs.stanford.edu:8090/778/1/2006-13.pdf > [2] http://theory.stanford.edu/~sergei/papers/vldb12-kmpar.pdf -- This message was sent by Atlassian JIRA (v6.3.4#6332)
