Yeah but if you ask the model what a cat is, it'll use other words that describe a cat because they're usually used in a sentence about cats. These words must relate to cats. So if I ask you what a cat is, you'll use words that relate to cats. Sure, you may visually see these words in your head. You may visually see a cat in your head, but your output to me is just a description of a cat. That's the same thing the network would do.

The whole point of this conversation is whether talking like an agent that has a theory of mind and actually having a theory of mind are the same thing. I responded to a thread about what "knowing" is, and the same distinction can apply. You're responding with "if it talks like it knows what a cat is, it must know what a cat is", and that's totally begging the question.

  While I agree with your point, how would you test that? How could you determine whether an LLM “knows” what a cat is. And what is “knowing”? If I know that a Mæw tends to nạ̀ng bn a S̄eụ̄̀x, isn’t that the first thing I’ve learned? And couldn’t I continue to learn other properties of Mæws? How many do I need to learn to “know” what a Mæw is?

    Like GP said, the LLM has no chance at knowing what a cat is, regardless of how much data it ingests, because a cat is not made of data. It's not like you're getting closer and closer to knowing what a "Mæw" is. You were at the same remote distance all the time. This is called the "grounding problem" in AI. As for how you would test it, I think one-shot learning would get one closer to proving understanding.

      The grounding problem is an intelligence problem, not an artificial intelligence problem. How would you envision a test based on one-shot learning working?

        The question of grounding is a problem that arises in thinking about cognition in general, yes. In AI, it changes from a theoretical problem to a practical one, as this whole discussion proves. As for one-shot learning, what I was driving at, is that a truly intelligent system should not need to consume millions of documents in order to predict that, say, driving at night puts larger demands on one's vision than driving during the day. Or any other common sense fact. These systems require ingesting the whole frickin' internet in order to maybe kinda sometimes correctly answer some simple questions. Even for questions restricted to the narrow range where the system is indeed grounded: the world of symbols and grammar.
        d1sxeyes 4y ago
        Why do you believe that a system should not need to consume millions of documents in order to be able to make predictions? For your example, the concepts of driving, night, vision, all need to be clearly understood, as well as how they relate to each other. The idea of 'common sense' is a good example of something which takes years to develop in humans, and develops to varying extents (although driving at night vs at day is one example, driving while drunk and driving while sober is a different one where humans routinely make poor decisions, or have incorrect beliefs). It's estimated that humans are exposed to around 11 million bits of information per second. Assuming humans do not process any data while they sleep (which is almost certainly false): newborns are awake for 8 hours per day, so they 'consume' around 40GB of data per day. This ramps up to around 60GB by the time they're 6 months old. That means that in the first month alone, a newborn has processed 1TB of input. By the age of six months, they're between 6 and 10TB, and they haven't even said their first word yet. Most babies have experienced more than 20TB of sensory input by the time they say their first word. Often, children are unable to reason even at a very basic level until they have been exposed to more than 100TB of sensory input. GPT-3, by contrast was trained on a corpus of around 570GB worth of text. We are simply orders of magnitude away from being able to make a meaningful comparison between GPT-3 and humans and determine conclusively that our 'intelligence' is of a different category to the 'intelligence' displayed by GPT-3.

  But that all boils down to are we having a scientific conversation or a philosophical conversation? In my opinion the only useful conversation is a scientific on. A philosophical conversation will and can never be resolved so if of no importance to this discussion. We can use philosophy to help guide our scientific conversation, but in the end only a scientific conversation can be helpful in reaching a meaningful/practical conclusion. So back to the questions of "What is knowing?" "Are talking like someone with theory of mind and having a theory of mind the same thing?" If your argument is that the only way to answer this it to have a first person experience of that consciousness then that's not a scientific question. No one will ever have one for an LLM or any other AI. It's like asking "What's happening right now outside of the observable universe?". If it can't impact us, it's irrelevant to science. If that ever changes it will become relevant, but until then it's not a scientific question. Similarly no person can ever have a first person experience of the consciousness of an LLM, so anything that requires being the LLM isn't relevant. So that means the only relevant question is what distinction can outside observers make between an agent talking like a theory of mind and having a theory of mind. And given a high enough accuracy / fidelity of responses I think we're only forced to conclude one of two things: 1. Something that is able to simulate having a theory of mind sufficiently well does actually have a theory of mind. OR 2. I am the only person on the planet with a theory of mind, and all of you are all just simulating having but don't actually have one. It's all "Searle's Chinese room" and "What consciousness is" discussions all over again. And from a scientific point of you either you get into the "it must be implemented identically as me to count" (which is as wrong as saying an object must flap its wings to fly), or you have to conclude the room plus the person combined are knowledgeable and conscious.

    I think you're making a strawman to argue against. Nowhere above have I claimed that "knowing" requires "consciousness", or "it must be implemented identically to me to count", and in fact I believe neither. But: - In this context, following on the whole 2nd half of the 20th century where cognitive science and psychology moved past behaviorism and sought explanations of the _mechanisms_ underlying mental phenomena, a scientific discussion doesn't have to restrict itself to only considering what the LLM says. Neither we, nor the LLM are black boxes. Evidence of _how_ we do what we do is part of scientific inquiry. - But the LLM does _not_ reproduce all the behaviors of an agent with a theory of mind. A two year-old with a developing theory of mind may try to hide food they don't want to eat. A 4-year-old playing hide-and-seek picks locations where they think their play-partner won't look. They take _actions_ which are appropriate for their goals and context which require consideration of the goals of others. The LLM shows elaborate behaviors in one dimension, in which it has been extensively trained. It has no capacity to do anything else, or even receive exposure to non-linguistic contexts. I am in no way arguing that only meat-based minds can "know". I'm saying that the data, training regime and model structure used for LLMs specifically is extremely impoverished, in that we show it language but no other representation of the things language refers to. Similarly, image-generating AIs know what images look like, but they don't know how bodies or physical objects interact, because they have never been exposed to them. Of _course_ we get LLMs that hallucinate and image-generators that produce messed up bodies. On the other hand, there are some pretty cool reinforcement-learning results where agents show what looks like cooperation, develop adversarial strategies, etc. There's experiments where software agents collaboratively invent a language to refer to objects in their (virtual) environment to accomplish simple tasks. I think there are a lot of near and medium-term possibilities coming from multi-modal models (i.e. can models trained on related text, images, audio, video) and RL which could yield knowledge of a kind that LLMs simply do not have.

But for us a cat is a living creature we interact with, not simply a description. We understand people's reactions to cats based on human-animal interactions, particularly as cute pets, not because of language prediction of what a cat description would be. People usually have feelings about cats, they have conscious experiences of cats, they often have emotional bonds with cats (or dislike them), they may be allergic to cats. LLMs have none of that.

  Not "for us"; only for those of us who have, in fact, been exposed to cats. And why do you think "feeling of a cat" cannot be encoded as a stream of tokens?
