Excuse me, I am seeking in the course when it is expalined the LeaveOneGroupOut strategy, I think in Module 2, but probably there is more valuable information inside the course. Can you help me?
Hi Idziej,
Its in module 7 choice of cross-validation in the non i.i.d data lecture.
I give you a little tip to find notion previoulsy see in the mooc : go on Intro — Scikit-learn course and use the “search this book” on the left side of web page. That saved me a lot of time in the absence of an index on the FUN mooc.
PS: If I may, if a member of the pedagogical team read me, the addition of such an index as an annex of the mooc (as you did for the glossary) could make it easier to find back the different notions shown in that wonderful mooc

Agreed that the fact that there is no way to search within the MOOC material inside FUN-MOOC is less than great for user experience …
I don’t think there is much we can do about unfortunately within the constraints of FUN-MOOC and maybe the best we can do is to feature more prominently that https://inria.github.io/scikit-learn-mooc can be used for search fonctionalities …
Doing an index would have to be done manually and quite fragile, for example if we split some notebooks, we would need to check which parts of the index have been affected …
