-------------------------------------
Summary: [MLLIB] Python support for Power Iteration Clustering
Key: SPARK-5963
URL: https://issues.apache.org/jira/browse/SPARK-5963
Project: Spark
Issue Type: Bug
Components: MLlib
Reporter: Stephen Boesch
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)
}
}
