org.apache.spark.mllib.clustering.LocalKMeans

public class LocalKMeans
extends Object

An utility object to run K-means locally. This is private to the ML package because it's used in the initialization of KMeans but not meant to be publicly exposed.

Run K-means++ on the weighted point set points. This first does the K-means++ initialization procedure and then rounds of Lloyd's algorithm.

Parameters:

seed - (undocumented)

points - (undocumented)

weights - (undocumented)

k - (undocumented)

maxIterations - (undocumented)

Returns:

(undocumented)
