WebFeb 12, 2015 · Both libraries have K-Means (among many others) but neither of them has a released version of Bisecting K-Means. There is a pull request open on the Spark project in Github for Hierarchical K-Means ( SPARK-2429) (not sure if this is the same as Bisecting K-Means). Another point I wanted to make is for you to consider Spark instead of … WebParameters: n_clustersint, default=8.
