Default question on netflix example

Hello everyone

The way I understood the Netflix example is that, given a set of users and movies along with the ratings that the users gave to those movies, the learning algorithm learns the vectors for the profiles of users and movies. So the hypothesis is the set of vectors for the users and movies.

I can see how this can be used to predict the rating that a user would give to a movie he/she didn't watch provided the user and the movie were in the original dataset.

Now my question is how can this be used for a completely new user (new customer)? Please correct me if my understanding of the learning algorithm is wrong.
