I joined the Anyscale tutorial yesterday, thanks a lot for a very interesting walkthrough @ceteri!

I have issues with understanding some the details of the Recsys notebook. Specifically, in calculating the observation vector:

scaled_diff = abs(c[item] - rating) / 2.0

Here c is a list of length number of users while item is an integer < 100.

The same issue has been raised in the see Anyscale Academy repo, see #35.

If it's not incorrect, it's hard to understand. Some extra comments would be worth a lot!
