----------------------------------------
Summary: Add argmax to Vector, SparseVector
Key: SPARK-7422
URL: https://issues.apache.org/jira/browse/SPARK-7422
Project: Spark
Issue Type: New Feature
Components: MLlib
Reporter: Joseph K. Bradley
Priority: Minor
DenseVector has an argmax method which is currently private to Spark. It would
be nice to add that method to Vector and SparseVector. Adding it to
SparseVector would require being careful about handling the inactive elements
correctly and efficiently.
We should make argmax public and add unit tests.
