Very impressive, but is it any more original than classic search engines' old trick of regular expressions to figure out if I mean the currency or weight when I ask "1 pound =" with the contexts USD or kg after "="? Does it understand the input, or are there just enough discussions in the training data to make it look like it is? I'm not convinced it's not the latter. It uses context to figure out we're trying to con…

I skimmed it and read the conclusion, and it looks interesting, will take a closer look when I have time.

The prompt covers a subject that goes completely over my head so I can't tell how well it reasons. I don't know what 1 proton to 100 neutrons means, but I gather it's radioactive. I don't think it's far fetched that it draws the same conclusion from the training set because to you it seems obvious, and is probably well known to anyone who knows the subject. Kind of like it would understand that "hotter than the sun" is super hot, can correlate to different melting points. But I wouldn't say it understands the concept of temperature. Given the right prompt it might give you the impression it does.

The feelings of the scenario reads like any PR comment after a tragedy. "We feel shock and disbelief" and so on. The scenario being hypothetical doesn't change that since it's probabilities. It acts just like you'd think it would. The earlier example with the helium balloon is similar, it assumes a human context and not the form, and environment the helium is in. True intelligence might not even consider the presence of atmosphere as the norm. "It has no weight outside of your human constraints" would be novel.

Lets say it has odd numbers between 1-9 in the database. Given the prompt 2 and 8 you will get back 1,3,7,9, sprinkled with some natural language and we get the impression it's intelligent.

Are you saying it understands the effect the neutron to proton ratio has, as opposed to just comparing the vectors closest to your prompt that it builds the answer from? Being tested on new and hypothetical examples only means it will be further from the vectors but still close enough to give us the impression it understands the subject. If the training data didn't include the words neutron or proton it would have no idea where to begin.

In my first comment that started this chain I said:

> I don't see why not. It's not taking a single answer from a database no, it's taking several based on probability and merging them into what it thinks we're looking for.

I don't think even this latest answer is any proof of anything other than that. Are you claiming there is? And what are you claiming is happening?

I am skeptical on many of those. Speech recognition is not even close to human level. Whisper, and whatever Google uses will make a lot of mistakes on audio files that are trivial to any native speaker.

In actual tests it is beyond human level. Humans actually mishear about 1 in 20 words during transcription tests; whisper does better.

Well, those "actual tests" clearly don't reflect reality. This is obvious if you actually use whisper.

The common sentiment around AI in the 90s and early 2000s was that it didn't work; it had its hype, it had its heyday, but it seemed like a dead-end for the most part. The Perceptron was merely a linear function approximator. And the Multi-layer Perceptron was a little more capable, but the many orders of magnitude it would have to scale up in order to be convincing just wasn't feasible back then (it finally was in t…

> That's what ultimately depresses me about AI. It's still just a parlor trick. We haven't actually taught computers to think, to reason, to be innovative. Deep learning is definitely having its day, but I suppose this too will pass unless we can unlock certain ways to make AI reliable and responsible. Or... to just start understanding it in general.

Isn't this just semantics, and the expectations that go with them, really?

If the marketing language surrounding ML wasn't so hyperbolic and sci-fi-y ("artificial intelligence"? "neural network"? give me a break!) I think we all could agree that what we can achieve now is really interesting and impressive in its own right.

Even if these models aren't on a path to some kind of "thinking computer" as you envision it, their "parlor tricks" are doing things I would've relegated to the realm of sci-fi even a decade ago, much less 25 years ago.

> The comment is written in such a way that it assumes this is the nature of reality and at some point, we will learn that the human mind is no different from the parlor tricks of LLMs. Again your whole point seems to boil down to simply denying physicalism (unless you have something more subtle in mind about the limits of physical science). It's a valid position to take but not very fruitful for further conversation…

No, I'm not talking about physicalism at all. I'm talking about reductionism and emergence. Even if it were shown that human thought processes operate at lower levels in ways similar to machines, that does not imply that human beings are equivalent to machines. That is a reductive argument. https://plato.stanford.edu/entries/properties-emergent/

Now I don't understand at all anymore why you're disagreeing so strongly. I don't think anyone has proven that it's inherent to emergent properties that they can't be understood or explained in detail. One just has to explain the mechanisms of emergence in addition to explaining the component parts reductively (and if that is your objection to reductionist arguments I would be inclined to agree with you). But such an explanation of how intelligence can emerge from simple component parts is exactly what could potentially be provided by a better understanding of AI systems.

I'm claiming that it's reasoning through the problem.

> True intelligence might not even consider the presence of atmosphere as the norm

I hugely disagree, that's not how an intelligent human would answer the question, and if it did this people would be complaining that it clearly doesn't understand the human context in which the question was likely asked.

> I don't know what 1 proton to 100 neutrons means, but I gather it's radioactive.

It would be hydrogen, but a type of hydrogen that doesn't appear in nature. It's a deliberately absurd example so that it's not in the training set. Its answers are different if the question involves tritium which while radioactive has a moderate half-life and wouldn't immediately pop the balloon.

> I don't think it's far fetched that it draws the same conclusion from the training set because to you it seems obvious,

Only because I can reason through what would happen, not because it's something I've seen talked about before.

To figure out what it would do, it cannot rely on an explanation elsewhere, it needs to first identify that the ratio of protons to neutrons is extreme. Then it needs to understand that this typically results in particular kinds of radiation.

It has to then use that information to consider how that would interact with the material of the balloon (and that this is important).

It has to use that information to consider how it would affect people, and what their reactions would be both before and after it explodes/pops.

This is multi-step reasoning through an issue that involves pulling together common expectations, physics and how humans react.

Here's a statement in it that shows to me more than just pulling a few answers together

> Balloon Behavior: Instead of floating up like a helium-filled balloon, this balloon would drop to the ground because the gas inside is denser than air. This might surprise the attendees, and curious children might approach or pick up the balloon, further exposing themselves to radiation.

> The feelings of the scenario reads like any PR comment after a tragedy. "We feel shock and disbelief" and so on.

Those are typical things, which is not surprising, but it is also clearly linked with the question. You have to understand how out of context this would be.

> If the training data didn't include the words neutron or proton it would have no idea where to begin.

Fully rediscovering what took humans many years to do off-the-cuff is an outrageously high bar.

What features of a question would you look for to identify whether it's "taking several answers from a database and merging them together" or performing some reasoning? I've asked a few times but don't understand what you're expecting.

Posting to confirm, having seen back-end sales numbers from (admittedly much smaller) vendors, the correlation between $just_bought_thing and $will_buy_another is very, very high, across pretty much every category I cared to look at.

But surely if you just bought a and like it and intend to buy it again as a gift then you don’t need an advert for Roombas - (and showing you such an advert followed by you buying another Roomba is making the advert look more effective than it was) - and you definitely don’t need an advert for Bissel or Dyson, and you definitely don’t need a dozen adverts for Amazon PLINGBA BEST VACUUM, TYBCHO VACUUM EXPERT, DAOLPTRY…

Showing someone ads for products in a category they recently purchased from is one of the most effective things a store can do, in terms of focused advertising driving sales. We can wonder why, but the data is exceedingly clear.

You're misunderstanding me, I'm setting no bars, and I have no threshold where this changes. We humans are also just looking things up in our database and doing deductions. We do some computing on urgency as well, like how when we hear a bang our mind goes for danger first before realizing it was harmless, but very similar to what these AIs do. Probabilities and experience. Fresh and novel ideas are very rare in humans as well, and not something I demand before I would consider someone a human.

I did however give you an example that would surprise me, if it considered mass and environment in a way that proves that it understands the problem for what it is. If it told me weight is a human construct and requires gravity/movement and how it depends. An intelligent human doesn't necessarily answer the question it is asked in the way it is phrased. It identifies and irons out misunderstandings, assumptions and other details important to correctly understand the problem, and may even rephrase the question to give a proper response. That would show me a deep understanding of the problem and maybe freak me out a little, but only if the hallucinations are gone and those can be difficult to spot.

This is, just like us, performing calculations and database look-ups. It may feel like it's doing something else but it's not. What would happen if we leave the weights as they are but switch the words? It would give us complete gibberish, but it's no less correct than it was before and it's not even giving us different answers, only the translations to language get distorted. Most people would call it stupid and pointless even if the only change is our interpretation of the answers.

I'm sure Hiroshima, Fukushima and other dangers of radiation is in the training set, as are all of the other steps you mention, it goes round and round testing the numbers based on training. Remember how this chain started, you claimed:

> They're not just retrieving stored text like pulling the most relevant passage from a database. If they were they'd not be able to deal with things outside the training set.

To which I simply replied:

> It's not taking a single answer from a database no, it's taking several based on probability and merging them into what it thinks we're looking for.

I read you (correct me if I'm wrong) as giving this way to much agency. To change my mind that it's doing something unexpected I would ask for logs on the calculations it does, and be able to correlate that to the training set. I have to be able to falsify the conclusions I'm asked to make. I know some people claim we don't understand these algorithms but I assume that's just hyperbole and with the correct measures we could follow every step.

If there are things there which I can not trace I would be very impressed, and honestly a little afraid. They are not trained for every single task, but approximations based on similarities have proven to be very capable even when we think we're out of context (we're not, it doesn't understand context and doesn't care, but neither do most humans).

I wrote about my definition of intelligence earlier this month: https://tildes.net/~comp/194n/language_is_a_poor_heuristic_f... I have a definition of intelligence. [...] Intelligence is prediction. In the case of intelligent living processes ranging from single celled organisms to complex multicellular life, intelligence arises from the need to predict the future to survive and reproduce. More intelligent organisms…

I don't agree with your definition at all. 2 people want to kill each other. The one taking the first step is the intelligent one because according to your definition he was better at predicting an outcome than his opponent. The real world is more complex than that and there are multiple options where both survive, or letting your opponent live and killing yourself because his life is more beneficial to humanity and…

Maybe I wasn't clear enough. The definition of intelligence I propose is wholly distinct from human prosocial values like cooperation.

This makes it useful for judging these properties across living and non-living intelligent processes, such as bacteria, ants, plants, dogs, LLMs, etc. It is not a useful definition for judging the value or "goodness" of human beings within society.

I'm arguing that intelligence (as prediction) is simpler than we often presume, not a mystery at all, and a basic building block of complex life. We happen to have a lot of it.

Perhaps we've been talking past each other then. I've been trying to show that these things can do reasoning, and my upper benchmark is "like a human". If you're starting from "these things might be doing what humans are doing / capable of performing similar tasks" then we're largely aligned.

The further question I still find interesting though.

> I read you (correct me if I'm wrong) as giving this way to much agency.

I know some people claim we don't understand these algorithms but I assume that's just hyperbole and with the correct measures we could follow every step.

This one is tricky. We know exactly what they do. Interpreting that is very hard though, they've a big pile of mathematical operations with billions of magical constants and it... works. We can see exactly what they do but if I could see every synapse firing in your brain I'd still not be able to understand how it works in a useful manner. So we understand them obviously, but at another level we really don't.

> I'm sure Hiroshima, Fukushima and other dangers of radiation is in the training set, as are all of the other steps you mention, it goes round and round testing the numbers based on training.

Just to be clear here, there is no recursion other than when you add more text. There is not an algorithm saying "identify parts X, then look in database Y, now summarise...". They're trained essentially to just predict the next word given some text. There's some later training to make them more conversational. The capabilities you see are just a consequence of that.

Othello GPT is show just moves. It ends up building an internal model of a board.

Let's try and investigate that then, that sounds interesting. I'm not sure I understand myself what you mean that weight is a human construct (it explains the difference between weight and effective weight in the answers to me off the bat, that's the only real difference). Perhaps this is too simple, the answer is quite straightforward.

> If it told me weight is a human construct and requires gravity/movement and how it depends

I asked "Which is the most, a pound of feathers or a pound of helium?" with largely just your statement as the system message and got

>The question seems to contain an intrinsic confusion. When we discuss weight, both a pound of feathers and a pound of helium would weigh the same - a pound. The difference, though, comes in their volume and density. A pound of helium would take up a lot more space than a pound of feathers considering the density of helium is lower than the density of feathers. If you were implying which would be more in terms of volume, then a pound of helium would be significantly more than a pound of feathers.

> However, I might be wrong if we take into account that helium, being a gas, is usually measured in terms of its volume at standard temperature and pressure, rather than by weight like solid or loose materials such as feathers. Also, the weight of a pound can vary slightly depending on where on Earth it is measured due to differences in gravity. However, these factors don't fundamentally change the answer to the question as it was posited.

Perhaps instead you could give me a short question and the kind of answer that would surprise you? I know this thread has gone on some time, but personally this is interesting to me. If you wanted to shift off from hn, feel free to drop me an email, I have a vested interest in understanding how people view LLMs.

With your example of "Turing Complete", we know what cannot be done and in this way, we have enumerated the things that can be done, if you like.

> You appear to be asserting that humans can tell if a loop will end, when that loop is defined so that if it does it doesn't and if it doesn't it does

We can determine by looking at certain problems (The Halting Problem is one such example) what the outcome will be without actually having to execute that code. The Halting Problem is one of the simpler problems that cannot be solved by computational means, which includes all artificial computational system.

You ask [How so?] to my comment about my goat. I would suggest that to understand this you need to go and observe what happens in the environment with such beasts, whether it be a cow in a local paddock or a pet dog or cat. Take time to observe the interactions that occur and think about how little [training] is involved here.

Watch children around you, take some serious time and observe them in their interactions and I think that when you think about how we program our various artificial stupidity systems that we are still at the caveman stage in our computational systems. We have barely discovered fire so to speak.

As for [GPT-3 is about as complex as the brain of a rodent], I don't think GPT-3 has even reached a single bacterium cell state of intelligence.

I would like you to try the following: Using your index finger on your left hand, touch the tip of your nose.

Now think about this: How did you do that very simple task? When did you learn and how did you learn to do that simple task?

If you think about it carefully, the task that I describes is incredibly complex.

Now what would be required to get an artificial stupidity system (AS) to do the same task? What programming do we need to do to achieve this task? What programming was done to you to achieve that same task?

When you start asking questions like this, it becomes very clear that all of our computational systems (including all of the AS systems) are incredibly simple and not at all comparable to what we find within ourselves.

We can build very useful tools that we can use to good purpose. But no tool is ever more than a tool for us.

I suppose what concerns me about our current state of affairs is that we are far too impressed by our caveman antics. There is not a single industrial system built by mankind that comes close to the integrated control and manufacturing systems found in a single living cell. None of our communication systems come close to what is found in the various control/communication systems found in even the simplest of chordate organisms.

It was very obvious, 40 odd years ago during my engineering undergraduate days, just how fragile much of our technological base was then. It is far more fragile today and yet we appear to be enamored by our [current technological prowess] which is actually far more fragile than it was 40 years ago.
