  Text-to-image generative models have enabled high-resolution image synthesis
across different domains, but require users to specify the content they wish to
generate. In this paper, we consider the inverse problem -- given a collection
of different images, can we discover the generative concepts that represent
each image? We present an unsupervised approach to discover generative concepts
from a collection of images, disentangling different art styles in paintings,
objects, and lighting from kitchen scenes, and discovering image classes given
ImageNet images. We show how such generative concepts can accurately represent
the content of images, be recombined and composed to generate new artistic and
hybrid images, and be further used as a representation for downstream
classification tasks.
