Hi,
In the rapidminer there is the normal kmeans, kmeans (fast) and Kmeans (kernel). I was wondering if any operator implements the kmeans ++ algorithm or is there another one that does?

determine good start values (optional)
If true the k start points are determined using the kmeans++ heuristic, descriped in "kmeans++: The Advantages of Careful Seeding" by David Arthur and Sergei Vassilvitskii 2007.Best,David7
