How to determine what restaurants a person will like based on their past ratings. This is not trivial; it is difficult to say what are the features which determine why a person likes a restaurant, so I'm thinking this would be a problem that could be tackled with deep learning i.e., automatic learning of features rather than hand-crafting in advance.
This is similar to the problem of movie/book recommendations, which has not been solved to my satisfaction. I have yet to see any good recommendation systems out there which go beyond recommending movies based on simple things like 'same actor was in this movie', 'people who watched that watched this' etc.
