Hi All,
I came across the SVD++ algorithm implementation in Spark code base, but I
was wondering why we didn't expose the scala api interface to python?
Any plan to do this?

Tarek,
On looking at the code in SVM.scala, I see that SVMWithSGD.predictPoint
first computes dot(w, x) + b where w is the SVM weight vector, x is the
input vector, and b is a constant. If there is a threshold defined, then the
output is 1 if that's greater than the threshold and 0 otherwise. If t
Oh, sorry about that. I forgot that's the behavior when the threshold is
not set. My guess would be that you need more iterations, or that the
regParam needs to be tuned.
I'd recommend testing on some of the LibSVM datasets. They have a lot, and
you can find existing examples (and results) for
Thanks for the clarification. Gonna test that and give you feedbacks.

You can do grid search if you set the evaluator to a
MulticlassClassificationEvaluator, which expects a prediction column, not a
rawPrediction column. There's a JIRA for making
BinaryClassificationEvaluator accept prediction instead of rawPrediction.

Someone correct me if I'm wrong but no there isn't one that I am aware of.
Unless someone is willing to explain how to obtain the raw prediction
column with the GBTClassifier. In this case I'd be happy to work on a PR.

Yeah - that needs to be changed as well. Could you send a PR to fix this ?

Thank you,
I looked at master branch. I did not realize that it's behind branch-1.5
BTW, line 54 still has SPARK_EC2_VERSION = "1.5.1"
