| Jul 2, 2018 at 16:27 | comment | added | Gaurav Gupta | As you said, we run SGD over known ratings to figure out a model that fits well, and we will use this model to predict ratings of missing ones. Now, just to confirm, in order to get SGD, we need to have a hypothesis ( e.g D.V is linear combination of IV [independent variable]). Right ? Or i am missing something. | |
