Where does the training data come from? Humans have traditionally sucked at drawing hands.

That's not the source of the problem. In layman terms, most fingers are flanked by two fingers and the ai does what is "statistically more accurate". It doesn't have a solid big picture context and gets lost in local detail, similar to kids' drawings. The role of training data is that hands are extremely expressive and commonly shown in very complex positions in the training images. AI is equally inept with complex body postures and contortions. But as it has been said, there are already models and workflows that improve the results significantly.

I think the human element shouldn’t be lost here. Remember, the goal of AI is to have a human brain on demand, but just a bit better than human. It sounds like every complexity there could apply to why humans suck at drawing hands.

You mean humans traditionally drew hands with 7 fingers and other such? I have a hard time remembering a single human drawing "sucking" in the way AI-generated hands do.

3 fingers is pretty common because it's easier to get a 3-fingered hand to look okay

but yeah humans rarely draw 7-fingered hands or smiles with four rows of 40 teeth

> but yeah humans rarely draw 7-fingered hands

Guess you haven’t seen hand drawings done by young children?

Surely you aren't suggesting that many drawings by young children are in the AI training models and that's why it sucks at drawing hands?

Nope, not that at all. I was replying directly to the quoted sentence of GP’s post with a clear and direct rebuttal against it.

i was trying to remember if young children often did this, but came to the conclusion that they only do it rarely

Based on experience with the kids drawings I’ve seen, I’d say getting the right number of fingers is definitely the rare thing up to a certain age, but specifically drawing 7, probably not that common I guess.

i guess i was wrong then

thanks

That's because yourself as a human being already owns a pair of hand, you can look at it everyday.

Now try draw the hands/feet of some animal you've heard of without a photo. e.g. hands of a sloth
