Hi Dato Forum Community, in CF, there is user-user and Item based CF approaches, can you implement both approaches with MF or only item based approach and also can one add side information in user based approach. I just want to confirm .Thank you

You can add side information using the user_data and item_data arguments (see the API docs for more details.

Technically, the user-user, and item-item CF methods can both be achieved by exchanging the users and items while calling the recommender.
