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.
- d1sxeyes 4y agoWhile 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?
- pegasus 4y agoLike 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.
- d1sxeyes 4y agoThe grounding problem is an intelligence problem, not an artificial intelligence problem. How would you envision a test based on one-shot learning working?
- pegasus 4y agoThe 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 agoWhy 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.
- pegasus 4y agoI was thinking in terms of simple logic and semantics. The example I picked though muddied the waters by bringing in real-world phenomena. A better test would be anything that stays strictly within the symbolic world - the true umwelt of the language model. So, anything mathematical. After seeing countless examples of addition and documents discussing addition and procedures of addition, many order of magnitude more than a child ever gets to see when learning to add, still LLMs cannot do it properly. That, to me, is conclusive.
- d1sxeyes 4y agoA child can 'see' maths though, they can see that if you have one apple over here and one orange over there, then you have two pieces of fruit all together. If you only ever allowed a child to read about adding, without ever being able to physically experiment with putting pieces together and counting them, likely children would not be able to add either. In fact, many teachers and schools teach children to add using blocks and physical manipulation of objects, not by giving countless examples and documents discussing addition and procedures of addition. You may feel it's conclusive, and it's your right to think that. I am not sure.
- CamperBob2 4y agobecause a cat is not made of data. Your perception of what a cat is, however, is most certainly made of nothing but data, encoded as chemical relationships at the neuronal level. And your perception is all there is, as far as you're concerned. The cat is just another shadow on Plato's cave wall. Arguably you "know" something when you can recognize it outside its usual context, classify it in terms of its relationships with other objects, and anticipate its behavior. To the extent that's true, ML models have been there for quite a while now. What else besides recognition, classification, and prediction based on either experience or inference is needed for "knowledge?" Doesn't everything human minds can do boil down to pattern recognition and curve fitting at the end of the day?
- BoiledCabbage 4y agoBut 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.
- abeppu 4y agoI 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.
