Subject [jira] [Commented] (SPARK-15784) Add Power Iteration Clustering to spark.ml
Date Mon, 04 Jun 2018 20:24:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-15784?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16500809#comment-16500809
] 

Xiangrui Meng commented on SPARK-15784:
---------------------------------------

Discussed with [~WeichenXu123] offline. I think we should change the APIs to the following:

{code}
class PowerIterationClustering extends Params with HasWeightCol with DefaultReadWrite {
  def srcCol: Param[String]
  def dstCol: Param[String]
  def wegithCol: Param[String]
  def assignClusters(dataset: Dataset[_]): DataFrame[id: Long, cluster: Int]
}
{code}
