The Tumblr post[0] by Kate Compton makes a good example of how to build a generator with meaningful outcomes. You start by writing down good examples you want your generator to have and bad examples you want to avoid. That will both be a kind of filtering test and a structure to build from.

You can create different metrics and numbers to guide the generator, but every number loses meaning once you decouple it from human feedback in games.
