Right, but neural networks at a certain level of scale begin to compress the perception described by the text rather than the text per se. The lexical features are abstracted away and the network begins to understand meaning directly. Of course, you'd still have differentiation by different perceptions and focus on different parts of reality, but I see no reason why that should not likewise abstract out at even higher levels. Ultimately, the whole point of language is that it's about reality, and there is only one reality no matter how many different cultures you feed in. The network isn't doing magic - it's just doing exactly the same thing that we're doing with language. The reason why language is useful is the same reason it's learnable.
- mjburgess 2y agoIf you want to understand how statistical AI systems work, then you should understand the basics of formalism. They are curve-fitting algorithms that approximate the probability distribution of a hisotrical dataset. That's all they are. By analogising to any animal or human mind, you aren't describing anythign that acutally exists. A neutral network algorithm isnt neural and it isnt a network. It's a statistical curve-fitting algorith. One oughtnt study trees to understand a decision tree either. This language is entirely metaphorical. There are no neurones in an NN, there are just summation entires in a matrix. This matrix comprises weights, which define the orientation and scale of the line pieces which form the curve being fit to the data.
- FeepingCreature 2y agoThey're, in particular, multi-level curve-fitting algorithms. A formalism which, I'm sure you are aware, can express any bounded computation. In particular, depending on how you set up the tape, neural networks are comfortably Turing complete. We're not talking about 2-layer perceptrons anymore here. In my opinion, you should look less at the formalism and more at the empirically demonstrated performance.
- mjburgess 2y agoI'm not aware that it can express any bounded computation. But such is irrelevant anyway: there is no function from the distributional structure of text tokens to reasoning. There is nothing to approximate, and this is a system trained just to approximate some presumed function: our mental capacities arent patterns in glyphs. Whatever property you might imagine a transformer architecture to have (and it is vastly fewer than the set needed for general computation), the problem here is that it's being applied to approximate the structure of historical text data which isnt being generated from such a function. Indeed, there is no function which generates text data, there's a very large number of independent generating processes that give rise to the distribution of text. The phrase "the war in ukraine" acquires a different semantics over 2010-2030 in a radically different way than, "I liked that film" does. The capacities which produce distributions of text tokens are highly varied, complex, invovle a vast array of our mental processes, and so on. There's literally almost nothing in the distribution of text tokens that corresponds to any features of these processes. The structure of language is conventional, and rests on our familiarity with such conventions. Otherwise, let's end all science, everything to be known about the world derives from how "e" occurs alongside "lectron"

Our mental capacities can be patterns. https://en.m.wikipedia.org/wiki/Predictive_coding https://en.m.wikipedia.org/wiki/Predictive_coding > There's literally almost nothing in the distribution of text tokens that corresponds to any features of these processes. There's nothing in evolutionary fitness that necessitates intelligence or reasoning ability either. Yet here we are. Sorry but if you don't see the connections then you need to do some reading on theory of mind, cognition, information theory, physics, philosophy. All of the fundamental basis are met to allow reasoning to emerge in LLMs. It is clear now where your confusion lies, and why you are led to believe so strongly that LLMs cannot reason: it is because you are an ML practitioner you overweight your expertise yet you don't know what you don't know, and have foundational gaps in your knowledge. You lack the context in these other fields. If you had them, your position should be closer to agnostic than this strong belief of yours that LLMs in their current form cannot reason.
