Octavian Geagla created SPARK-5726:
--------------------------------------
Summary: Hadamard Vector Product Transformer
Key: SPARK-5726
URL: https://issues.apache.org/jira/browse/SPARK-5726
Project: Spark
Issue Type: Improvement
Components: ML, MLlib
Reporter: Octavian Geagla
I originally posted my idea here:
http://apache-spark-developers-list.1001551.n3.nabble.com/Any-interest-in-weighting-VectorTransformer-which-does-component-wise-scaling-td10265.html
A draft of this feature is implemented, documented, and tested already. Code
is on a branch on my fork here:
https://github.com/ogeagla/spark/compare/spark-mllib-weighting
I'm curious if there is any interest in this feature, in which case I'd
appreciate some feedback. One thing that might be useful is an example/test
case using the transformer within the ML pipeline, since there are not any
examples which use Vectors.
