Hi,
can anyone tell me which topic is optional either Intro or differential privacy?
Thanks

None of them is optional. Both are mandatory for the exam

I guess both are optional, but both could be part of the exam.

maybe everything is optional, but will be part of the exam

Optionality is hard to define (see "family resemblances"), so you have to consider following table with 1-anonymity and 1-diversity:

topic	optional	rly optional?
intro	yes	no
chap 1	yes	no
chap 2	yes	no
chap 3	yes	no
diff. priv.	yes	no

 

As far as I remember, the Intro slides are NOT mandatory. However, if you have problems with the other topics you can learn those slides as well an tell him that you learnt them and he will then ALSO (not only) ask you about that chapter. The differential privacy as well as the other sets of slides are of course not optional.

By the way if you had a look at the first slides of the Intro chapter it literally says that it is not relevant for the exam (except a few points which are marked which I could however not find)

Best
