fmcquillan99 commented on issue #433: Kmeans: Add automatic optimal cluster estimation URL: https://github.com/apache/madlib/pull/433#issuecomment-531388355 I suggest we change the default the silhoette not elbow method: https://en.wikipedia.org/wiki/Elbow_method_(clustering) "It is often ambiguous and not very reliable, and hence other approaches for determining the number of clusters such as the Silhouette method are preferable."
