But on each picture you automatically recognize when there is some face. And you need to be able to learn new faces. So doesn't it make necessary for somewhere in the system to be your face model in order for system to decide to ignore it? Not my field so I'm clueless but I would assume that without such hidden model it would be more likely to match the next most similar person? (I'm guessing social network is also taken into account to make such mistakes less likely?)
