I'm following <a href="http://dato.com/learn/gallery/notebooks/recsysrank10K_song.html">Chris's millison song tutorial</a>. When I use the same training data to train a ials ranking factorization recommender, I'm not seeing RMSE in the training phase... When I call evaluate function to get RMSE and precision, RMSE is > 1... which is concerning me.
Few questions: 1) Would you help me if I'm using the function call correctly?
2) Shouldn't RMSE <= 1 for this implicit collab approach?
