Hello Sean,
Thank you for the heads-up !
Interaction transform won't help for my use case as it returns a vector
that I won't be able to hash.
I will definitely dig further into custom transformations though.
Thanks !
David

Are you looking for
https://spark.apache.org/docs/latest/ml-features.html#interaction ? That's
the closest built in thing I can think of. Otherwise you can make custom
transformations.

Hello everyone,
In MLLib, I’m trying to rely essentially on pipelines to create features
out of the Titanic dataset, and show-case the power of feature hashing. I
want to:
- Apply bucketization on some columns (QuantileDiscretizer is fine)
- Then I want to cross all my columns
