How does human creativity work?
2 comments

Slight jitter + strong and complex selection functions, like "is it useful?", "is it more useful than what came before?", "is it appreciated by the audience?", etc.

The creative generation part - adding some randomness to the process - is trivial with machines. Much easier than with humans adults, who often have to learn to allow more randomness and in their thinking/feeling, in order to make some creative work. But the selection functions are deeply social, which is something we're instinctively good at, and had little luck teaching the machines so far.

Well, with the possible exception of GPT-4, which may have learned just enough about what humans like, that it could do a passing job at discriminating art/innovation from noise. I say may - it feels possible, but we won't know until someone properly tests for it.

I've tried giving GPT4 some axes to rank writing on, and feed it some paragraphs. It's not perfect at it, but it's a far better critic than writer.

E.g. a while back I had it write something "in the style of Douglas Adams" and then had it critique it in another chat, and it recognised the imitation and proceeded to quite harshly judge its own writing for being flat and lacking direction and purpose. It was quite entertaining (more so than its superficially amusing Douglas Adams imitation).

With something representable with math functions that nobody knows yet.
That is an incredibly strong assertion that evidence does not seem to support currently. So, you may take it on faith if you wish, however there is growing interest in the notion that creativity itself is that which is not systemetizable.
You gotta back up claims like that with a source. As far as I know, nobody can prove we are not in a simulation. Meaning everything is made out of math.
I think my point flew over your head. The burden of proof is on you to provide the source that human creativity can be computed mathematically.
Today's AI has taught us that everything people show us they think is unique, isn't really. Everything comes from somewhere, including the things that add up to what we call creativity.
That's actually untrue to me as a professional artist. A.I. art has shown me that cheap permutations (which have been done in art even before A.I.) can still capture the untrained eye. I don't think that's anything particularly new.

And absolutely, however creativity is the tip of the spear which pushes beyond constraints to develop novel AND meaningful style (like Beksinski, Kopera, Kostetsky, Moebius, etc).

Nice try.

I think my point flew over your head. The burden of proof is on you to provide the source that we can't simulate the whole universe, humans included. This is something that cannot be proved to be true, even if it was the truth, it is possible that you can only prove it to be false, and nobody managed to do it yet. That's why it's on you to prove it to be false. Especially since you claim that something cannot be computed with maths.
I never said it can't. And you're mistaken unfortunately - it is extremely difficult to prove a negative, as most people trained in philosophy intimately understand. For instance, "prove God is NOT real". You might be new to analytical thinking, and I would recommend diving a bit deeper into "burden of proof" type arguments before proceeding further.

Note that the same can be said about the negation: show me a proof that it can't.

It's an assertion that rests only on the assumption that the brain adheres to known physics or if it relies on unknown physics that the computational effects of those differences can be simulated or the physical effect replicated.

It'd take a truly extraordinary find that'd upend both physics and areas of logic for that assertion to be false.

Let's try something else, because you seem to take it that "brain = physics" is a strong enough argument to believe that all of human creativity is inherently systematic.

The definition of creativity itself should include the ability to subvert a system through abstraction. AI is a system so it cannot subvert itself (or, it hasn't yet). As humans, we subvert systems in mathematics by creating higher dimensional abstraction and shattering previous understanding of the fields. Often, mathematicians achieve this with a "lightening bolt-like realization" that they do not attribute to systematic thinking.

Please reconsider whether systematizability should be so quickly assumed through napkin philosophy. If you want, prove with a topological map of the creative apparatus in the brain that it produces results in a systematic way. That would at least scratch the itch and get the conversation going somewhere interesting.

There's no "napkin philosophy" here.

What you call "systematizability" is irrelevant. Only whether or not a function can be computed matter, and if a function can be computed by a brain restricted to known physics, there is no reasonable theory under which it can compute anything which can't be computed by any universal turing machine. Given the absence of even any real hypothesis for any category of functions which can't, it'd be an absolutely extraordinary claim to suggest such a function exist.

Where you'd get a Nobel in physics if you could show unknown physics in the brain, you'd secure a Nobel in mathematics if you could come up with a class of functions the brain can compute which can't be computed by a computer, because it'd fundamentally break basic assumptions in any number of subfields of both maths and computer science.

What you describe as "subverting itself" does not require anything as drastic. It merely requires thought processes unobservable by the person in question, and processes to complex to casually understand and/or randomness. Given a large proportion of people don't even have an inner voice they can "listen to" in order to observe their thought processes other than via outputs, and we know e.g. from split-brain experiments that the conscious part of human reasoning often outright invents knowledge and observation of thought processes, we have no reliable way of analysing the extent to which thinking is "systematic", and plenty of evidence to suggest we can not trust any such notion.

Interesting. Evolution is a series of happy accidents. So is creativity.
