I have tried approaching this problem using collaborative filtering but it gave me a really low score. I read through the comments that the best method here is to use classification. I was wondering, what are the best approaches while using classification.
hey i just think about collaborative filtering but is it worth to give it a try? you should try ensembel
I've got a decent score using the classification approach, an ensemble model and good hyparameter tuning. I think how you prepare your data for the classification problem is important.
I see. Thanks, Darrel
