I am trying to set up a model for a factorization recommender and I need to use side data. The problem I am facing is that some of the items to recommend have, for instance, more than one genre. How can I represent this properly so that the system uses both genres? As of now I have tried to represent this as a list, but I see the system still treats them as one genre.
