SGD logistic regression

Hi everyone,

I have a very basic question on the Apache SGD implementation. My training
set has about 50 features, most of which are categorical. Some of these
categories are binary, but others can have an unknown number of discrete
values (countries, cities, etc.).

Should I be encoding these with the ConstantValueEncoder? The
StaticWordValueEncoder?

Thanks,
