Sam Stoelinga updated SPARK-8587:
---------------------------------
Description:
Looking at PySpark the implementation of KMeansModel.predict
https://github.com/apache/spark/blob/master/python/pyspark/mllib/clustering.py#L102
:
Currently:
it calculates the cost of the closest cluster and returns the index only.
My expectation:
Easy way to let the same function or a new function to return the cost with the
index.
