Description

Add python support for the Power Iteration Clustering feature. Here is a fragment of the python API as we plan to implement it:

/**

• Java stub for Python mllib PowerIterationClustering.run()
  */
  def trainPowerIterationClusteringModel(
  data: JavaRDD[(java.lang.Long, java.lang.Long, java.lang.Double)],
  k: Int,
  maxIterations: Int,
  runs: Int,
  initializationMode: String,
  seed: java.lang.Long): PowerIterationClusteringModel = {
  val picAlg = new PowerIterationClustering()
  .setK(k)
  .setMaxIterations(maxIterations)

try

{ picAlg.run(data.rdd.persist(StorageLevel.MEMORY_AND_DISK)) }

finally

{ data.rdd.unpersist(blocking = false) }

}
