Unable to understand negative datasets in "Course" folder

Dear Author,
I am not able to understand what is the negative dataset in Course Folder

hi @shivampa It means that given a concept pair (A, B) with the format 'A\tB', B is not a prerequisite of A. They are basically served as negative examples for classification.

Hi @harrylclc, I have confusion whether the negative dataset contains both i) B is not a prerequisite of A, and ii) B and A are not related at all, or only (ii) case ?
