The reason is because hands are sort of a limit case. Humans are very adept at knowing when a hand looks weird. If you draw someone’s shoulder and get it slightly wrong, no one will notice. If you get their hands wrong, everyone notices.
But the same is true for eyes and faces, which AI can do quite well. So why are hands so hard? Because they’re “tentacle-y”. Fingers : humans :: tentacles : octopus. They’re long dangly things, and AI has a limited sense of geometry.
Tentacle porn is hilarious to me, so I chose it as a target shortly after I started fooling around with GANs. There’s also limited data; it’s surprisingly hard to collect thousands of high-quality drawings. So it’s a real challenge to get an AI to understand how to make them, which is why I like to try.
