Stavros Kontopoulos updated FLINK-5588:
---------------------------------------
Description:
So far ML has two scalers: min-max and the standard.
A third one frequently used, is the scaler to unit.
We could implement a transformer for this type of scaling for different norms
available to the user.
Axis for scaling either features or samples ( 0 for columns-features 1 for
samples-rows)
