Subject Reverse MinMaxScaler in SparkML
Date Mon, 08 Jan 2018 09:10:31 GMT

since the similar question on StackOverflow remains unanswered (
) and perhaps there is a solution that I am not aware of, I'll ask:

After traning MinMaxScaler(or similar scaler) is there any built-in way to
revert the process? What I mean is to transform the scaled data back to its
original form. SKlearn has a dedicated method inverse_transform that does
exactly that.

I can, of course, get the originalMin/originalMax Vectors from the
MinMaxScalerModel and then map the values myself but it would be nice to
have it built-in.
