Re: Building AI without a neural network
#12It is important to recognize the limitations of these deep neural networks and especially GPTs which both have been hyped to the point where most see it as the solution to everything; since many deep-learning supporters continue to compare it to the human brain, despite the severely limited explainability in these models to the point where not even researchers know what it is doing.
It's one of the reasons why there's very low trust in deep neural networks in general. Humans can be held to account for their actions but with almost all these neural network systems cannot be held to account when something goes wrong and accept the output as the answer whilst 'it is thinking' or 'reasoning'.
> The mechanism behind real world complex systems requires both simple rulesets and a communicative fabric that allows for real time feedback loops. For flocks of starlings this can be as easy as keeping eye contact with the next bird. For Termites, it is pheromone trails. For societies, it is language, reputation and status. For capital markets, it is money. And for the internet, its the physical wiring and network architecture that makes it all possible.
As long as this solution provides transparency and explainable results rather than giving an answer from a black box system then I'm looking forward to this approach.

#13It's interesting how when discussing neural networks "inspired by the human brain" always comes up when the brain, as far as we know, is emergent behavior from many little things coordinating, not architected. "Top down" never really works for complex systems, the economy being an obvious example. But we tend to ignore that when thinking about neural networks.

Even then, the architectures we use are essentially stumbled on. This is alchemy, not modern chemistry.

I took a deep learning class before things really took off [0], and what we were taught was that a lot of deep learning research was just trying different structures to see what worked. Even the people who were good at it didn't base their architectures on strong theories for how and why things would work, they just had developed an intuition through lots of trial and error.
All the explanations for what the various structures in a deep learning model are doing are post hoc—they're observations made of the behavior of the systems after we build them.
[0] Edit: Not just a random deep learning class either. The TA for that class created AI Dungeon that semester. The professor came in one day with a story of how they accidentally racked up tens of thousands of dollars in Google Cloud bills in 24 hours when that went viral.

Bear in mind that for most (all?) advanced economies the state runs about 40-50%, so top down is working fine for about half of the economy.
