I posted the full question on StackOverflow and as it contains some figures
I refer you to that post.
I currently believe that this issue is a bug and I opened an issue on
To sum up, the issue is that GridSearchCV does not handle the splitting of
the sample_weight vector during cross validation.
Nota bene: cross_val_score seems to handle the splitting OK, this issue
seems to occurr only in GridSearchCV.
Any comments enlightening me and showing me how wrong I am are most welcome.
