Can this be used to predict the ratings for a particular timestamp, in user-item-rating scenario? #2

Hi !

Thank you so much for your code. I am a noob when it comes to Matrix Factorization. I intend to use your BPTF implementation for a small project of my own, where I have tensors in the format of <U,I,R,T> where U=user, I=item, R=non-negative rating, T=time in year. Now I have prepared .csv files consisting of <U,I,R> for each year slice (25 files). I am not sure how to use them as input files for the program.And how should I interpret the output? I need to predict the rating for an item corresponding to a user at year 20xx using the previous years data. Can you please help me out?

Best Regards, Manajit
