Let's say I implemented DeepFM here. I see how we train and test. But after we test, now we want to actually make recommendations with unseen new data. But how do we then create the unseen new data? What is people normally do? Because there are tens of millions users and millions movies, I don't think people generate unseen new data point for each user to go on for loop of every movie. Would you tip me off how people generally do in production?
