Ok sorry for that I did squash the commits, also I am used to it from other 
projects where the comments are invalidated.

But please don't do a force push on a branch which has been opened as a PR. 
If there was a review ongoing, then the force push might invalidate it (e.g. if 
you changed something in the relevant files).

rebase and force push.

Hi @skonto, if you have activated the Travis integration for your own repo, 
then you can restart the testing job there. For the apache account it is not 
possible. However, I've seen that only the last build ran out of time. We're 
currently at the very limit in terms of runtime what Travis allows. That is a 
known issue and we try to address it soon.

Hello @skonto thanks for your contribution!

I'm currently snowed under paper deadlines, so I can't give you a time for 
when I'll be able to go through this, hopefully within the next 2-3 weeks.

[~till.rohrmann] Have already implemented the Normalizer... need to check 
floating arithmetic for the UnitScaler because the sum might lead to overflow:

Standard scaler uses this algo:
