Mind-reading AI can translate brainwaves into written text: Using only a sensor-filled helmet combined with artificial intelligence, a team of scientists has announced they can turn a person’s thou…::A system that records the brain’s electrical activity through the scalp can turn thoughts into words with help from a large language model – but the results are far from perfect
Calling llm “big auto-complete” is like calling people “big bacteria” . It’s true that they act on the same goal, guess the next word for llm and auto-complete; survive and reproduce for people and bacteria, but they are vastly different in scale and complexity.
Also what would AI be to you if not an llm? Cause I’d say anything that has an SAT score higher than most Americans has some form of intelligence.
“Big Bacteria” is a much more accurate descriptor of humans than “Artificial Intelligence” is of large language models.
This is the same problem we had with IQ testing, what the test measures is not “intelligence”, but the ability to retain and process information according to a predefined schema. This requires no intelligence at all, as demonstrated by the fact that a sufficiently large statistical model of human writing patterns can pass the SATs.
This seems like circular reasoning. SAT scores don’t measure intelligence because llm can pass it which isn’t intelligent.
Why isn’t the llm intelligent?
Because it can only pass tests that don’t measure intelligence.
You still haven’t answered what intelligence is or what an a.i. would be. Without a definition you just fall into the trap of “A.I. is whatever computers cant do” which has been going on for a while:
Computers can do arithmetic but they can’t do calculus, that requires true intelligence.
Ok computers can do calculus, but they can’t beat someone in chess, that requires true intelligence.
Ok computers can beat us in chess, but they can’t form coherent sentences and ideas, that requires true intelligence.
Ok computers can form coherent sentences but …
It’s all just moving the goal post to try and preserve some exclusively human/organic claim to intelligence.
There is one goalpost that has stayed steady, the turing test, which llm seems to have passed, at least for shorter conversation.
The purpose of the SAT isn’t to measure intelligence, it is to rank students on their ability to answer test questions.
A copy of the answer key could get a perfect score, do you think that means it’s “intelligence” is equivalent to a person with perfect SATs?
For the same reason that the SAT answer key or an instruction manual isn’t, the ability to answer questions is not the foundation of intelligence, nor is it exclusive to intelligent entities.
Computer scientists, neurologists, and philosophers can’t answer that either, or else we’d already have the algorithms we’d need to build human-equivalent AI.
Exactly, you’re just falling into the Turing Trap instead. Just because a company can convince you that it’s program is intelligent doesn’t mean it is, or else chatbots from 10 years ago would qualify.
The Turing Test is just a slightly modified version of a Victorian-era social deduction game. It doesn’t measure intelligence, but the ability to mimic a human conversation. Turing himself acknowledged this: https://www.smithsonianmag.com/innovation/turing-test-measures-something-but-not-intelligence-180951702/
I think your mixing up sentience / consciousness with intelligence. What is consciousness doesn’t have a good answer right now and like you said philosophers, computer scientists and neurologist can’t come to a clear answer but most think llms aren’t conscious.
Intelligence on the other hand does have more concrete definitions that at least computer scientists use that usually revolve around the ability to solve diverse problems and answer questions outside of the entities original training set / database. Yes doing an SAT test with the answer key isn’t intelligent because that’s in your “database” and is just a matter of copying over the answers. LLMs don’t do this though, it doesn’t do a lookup of past SAT questions it’s seen and answer it, it uses some process of “reasoning” to do it. If you gave an LLM an SAT question that was not in it’s original training set it would probably still answer it correctly.
That isn’t to say that LLMs are the be all and end all of intelligence, there are different types of intelligence corresponding to the set of problems that intelligence is solving. A plant identification A.I. is intelligent for being able to identify various plants in different scenarios but it completely lacks any emotional, conversational intelligence, etc. The same can be said of a botanist who also may be able to identify plants but may lack some artistic intelligence to depict them. Intelligence comes in many forms.
Different tests can measure different forms of intelligence. The SAT measures a couple like reasoning, rhetoric, scientific etc. The turing test measures conversational intelligence , and the article you showed doesn’t seem to show a quote from him saying that it doesn’t measure intelligence, but turing would probably agree it doesn’t measure some sort of general intelligence, just one facet.
The “reasoning” in LLM is literally statistical probability of which word would follow which word. It has no real concept of what it talks about beyond the pre-built relationship matrices between words and language rules. That’s why LLMs confidently hallucinate obvious bullshit time to time - to them there’s no meaning to either truthful or absolute bonkers text, it’s just words that should probably follow each other.
You’ve now reduced the “process of reasoning” to hitting the autocomplete button until your keyboard spits out an answer from a database of prior conversations. It might be cleverly designed, but generative models are no more intelligent than an answer key or a library’s card catalog. Any “intelligence” they appear to encode actually comes from the people who did the work to assemble the training database.
This is not how LLMs work, they are not a database nor do they have access to one. They are a trained neural net with a set of weights on matrices that we don’t fully understand. We do know that it can’t possibly have all the information from its training set since the training sets (measured in tb or pb) are orders of magnitude bigger than the models (measured in gb). The llm itself is just what it learned from reading all the training data, just like how you don’t memorize every passage in a book you read, just core concepts, relationships and lessons. So if I ask you " who was gatsbys love interest?" You don’t remember the line and page of the text that says he loves Daisy, your brain just has a strong connection of neurons between Gatsby, Daisy , love, longing etc. that produces the response “Daisy”. The same is true in an LLM, it doesn’t have the whole of the great Gatsby in its model but it too would have a strong connection somewhere between Gatsby, Daisy, love etc. to answer the question.
What your thinking of are older chatbots like Siri or Google assistant which do have a set of preset responses mixed in with some information from a structured database.
Please do explain how you think they make LLMs without a database of training examples to build a statistical model from.
I.e. “a model that encodes a database”.
I.e., “we applied a very lossy compression algorithm to this database”.
Check out the demoscene sometime, you’ll be surprised how much complexity can be generated from a very small set of instructions. I’ve seen entire first person shooter video games less than 100kb in size that algorithmically generate hundreds of megabytes of texture data at runtime. The idea that a mere 1,000x non-lossless compression of text would be impossible is laughable, especially when lossless text compression using neural network techniques achieved a 250x compression ratio years ago.
If LLMs were just lossy encodings of their database they wouldn’t be able to answer any questions outside of there training set. They can though, and quite well as shown by the fact you can give it completely made up information that it can’t possibly have “seen” and it will go along with it and give plausible answers. That is where it’s intelligence lyes and what separates it from older chatbots like Siri that cannot infer and are bound by the database they pull from.
How do you explain the hallucinations if the llm is just a complex lookup engine? You can’t lookup something you’ve never seen.
