To no one's surprise and to almost everyone's disappointment, the model has learned from pictures on the Web that such an author looks like a white guy, usually older than 30, with a simple/bad haircut, exhibiting varying degrees of unkempt facial hair, typically wearing thick glasses, standing in the middle of a bland-looking room... and ticking every other checkbox that goes with the stereotype. At present, that stereotype accurately represents reality. Oh, and some of the faces are... recognizable (e.g., one of the images looks like a younger Geoff Hinton with facial hair and an early-Beatles haircut). Along with most people on HN, I look forward to a future in which the training data, and the generated images, will be more diverse.
