density function and telling you how likely particular pieces of data are to come from the same distribution as a training data gans are more focused on generating samples rather than estimating the density function there are some kinds of games like flow gun that can do both but mostly guns are about generating samples of generating new photos of cats that look realistic and they do that completely from scratch it's analogous to human imagination when again creates a new image of a cat it's using a neural network to produce a cat
