These are Language Models, and it's well known that natural languages follow Zipf's Law, where word frequencies adhere to a power-law distribution. Because LLMs are trained to learn and predict patterns in language, it’s clear that they must also exhibit this behavior. In fact, this could explain why LLMs seem to hit an efficiency ceiling-they are constrained by the power-law nature of language itself. As the models improve, their gains become increasingly marginal, particularly when dealing with rare words and complex language structures.

Possibly shouldn't be a surprising relationship: Thermodynamic entropy and entropy in information theory are related and it tells us that each bit of information has an minimum cost in terms of energy. When you plot cross entropy, you're plotting missing information. It would make sense to flip the y axis and consider that to be how much information was learned. When you plot compute, you're also plotting energy, which is directly proportional to the information and therefore should produce a straight line. Not all models/learning schemes are 100% efficient so they are constrained to one side of that line. The other side represents a thermodynamic impossibility. It would break the 2nd law because the entropy of the universe (increased by the heat output of your GPUs, decreased by your model learning) would decrease.

Another fascinating point is how well our observations in neural biology follow similar power scaling laws. The human brain seems to fit very nicely on the primate scaling curve and (not surprisingly) points to an adaptation within primates for superior cognitive scaling performance vs other mammals.

Models like GPT-4 are highly specialized and would be a better comparison to the sub-network of regions in our brains that processes language. Lastly, an area where we are significantly lagging in capability, is the Abstraction and Reasoning Corpus (ARC). Human scores against ARC are in the 80% range whereas our best algorithms are in the range of 30% and of course all of the most interesting applications of AI/ML will heavily task abstraction and reasoning tasks.

Its not the AI model, its a property of the dataset - that's the only commonality. The fact that it follows a power law is a significant indicator.

The most commonly known is word-frequency power law, so well know that it has a name, Zipf's Law. Regardless of language, regardless of what collection of works, the top 100 words comprise approximately of half the collection and the next top 10000 words comprise the remaining half.

​@@darkstar4494 Its more a case of a power law dataset being simultaneously easy to learn but also difficult to master. Half the dataset is easy to learn because examples are abundant. The other half of the dataset has a sparsity issue where examples become increasingly rare, eventually to the point where you only get to words that only appear once. It doesn't matter how many TB of data you have, there will always be these rare words. And regardless of the model used, all models have issues learning when there are only a few or just 1 example to learn from. And that's why initially the AI learns rapidly, reducing its error rate very quickly, but eventually an inflection point occurs when it becomes increasingly difficult to learn from a lack of sufficient data.

[@cudgeonkurosaki8489]

The answer is somewhat straightforward, if technical and boring. The error of a statistical model may be given by KL-divergence. The KL-divergence of a statistical model is zero when the cross-entropy is minimized. The entropy of human language sample, say a small sample via English Wikipedia, may be measured in shannons (bits). Adding one neuron to a model is roughly linear in units of shannons for a given neuron type because the parameter space of a neuron is something that can be saved in a 64-bit computer. A model needs at least as much entropy as English Wikipedia to predict it accurately, which is why a language model inevitably eats shit when it encounters something it hasn't learned before (it already used all of its bits in representing what it has seen). Where you place the neuron matters, but its contribution to reducing the KL-divergence is still at most linear. In fact, the upper bound should never be greater than the entropy of a single neuron. This is only on average since placement matters relative to poorly placed previous neurons. For example, although linear autoencoders may form a bottleneck at the latent space, the entropy of the neurons in the encode and decoder layers still matters. Maybe I'll write a book on it once I finish my current one. A high KL-divergence of two different humans with the same language model is basically the result of all human conflict, but it's hard to explain in a comment.

I think this trend makes a lot of sense. AI models don't actually learn. They just recognize and copy patterns, and in a complicated way sort of extrapolate and interpolate those patterns onto new data. The more data you train it on, the higher the accuracy of the AI's predictions. Letting it train for longer then, is just the AI recognizing the patterns in the training data better, and having more training data gives it more data to interpolate/extrapolate from. But no matter how good your algorithm is (Which AIs currently basically are), there is always a limit to how much data can be recovered from a limited amount of samples. If you look at AI as being very fancy data interpolation machines, this result makes a lot of sense. The only way I can see that might break this pattern is by having AI actually *learn* rather than do pattern recognition. You'd need an AI that's trained for being able to learn rather than to do one single task, but that's difficult because you'd have to measure learning ability, and making and reviewing your own mistakes is a big part of learning. Having curiosity and a drive to experiment is a part of that too. Such decisions aren't very rational and measurable. You'd need to evaluate something as abstract as the ability to learn. That's definitely not an easy thing to do.

[@tukib_]

This is an active area of research, and you might enjoy looking into Continual Learning, Multi-Task Learning and Meta-Learning. Probably the largest gap between AI and animal intelligence is the fact that our brains and bodies in general are hierarchical systems with abilities like neuromodulation (neurotransmitters), neurogenesis and metaplasticity (neurons/signals modifying other neurons). As you're pointing out, it's quite clear that our cognition requires more than a universal approximator. Also, what you're referring to as "actual" learning is typically called human learning, as the distinction is important but disqualifying neural networks from learning would make comparisons between the two more clunky.

[@rysea9855]

@@tukib_ I suppose yeah, current AI models do learn. Just not like humans. If you think about it, yeah, if you want AI with human-like intelligence you're gonna need similar mechanisms. Similar to dopamine in our meat computers, it'd need to be able to give itself a reward for learning new things, and the system for that has to be integrated with the rest of the model in a way that it can understand what's important to learn / improve at, while also not getting stuck in a trap of giving itself infinite reward without being productive. It would need to be a closed loop system of multiple systems acting on eachother, that can also determine reward for the subsystems, while also still being productive to humans. Getting a bit philosophical here, but I think the only way to achieve that is by having it either value its own existence, or value being useful to humans, more so than it would value its sense of productivity, in a way that's hard-coded to ensure it can't possibly break that loop (somewhat similar to human emotion). If it doesn't value either of those, it will not care about actually being productive to humanity, and likely create a closed loop of giving itself infinite reward by setting arbitrary goals for what counts as being "productive" (similar to how we might get drawn to memes or tiktok, which activate our dopamine reward system because our brain recognizes it as productivity). But at that point, I'd say it gets eerily similar to being a conscious machine. Either the machine values it's own existence, which will definitely turn out bad for humanity if it gets sufficiently advanced, or the machine feels an obligation to serve humanity, which.. kinda feels like having super intelligent dogs? As dystopian as the latter sounds, I don't think having machines with some form of emotion that are solely dedicated to serving humans is necessarily a bad thing as long as they're content with their existence. Anyways, enough rambling about philosophy. I am also very much interested in the actual mechanics of AI, so I'll definitely be checking out Continual Learning, Multi-Task Learning and Meta-Learning as you mentioned.

I thought we knew this law is just a function of AI being equivalent to stirring linear algebra curve fitters in, basically, the dumbest way possible. We know this because the counter factual is used all the time, even in AI. there are many cases where hand coded linear approximators are used instead of NNs, in transformer architecture for instance. The approximators algos do much much better in terms of performance per watt in these cases, hence why they're almost universally used instead of learned NNs for simple cases. That line is basically, 'well if you keep just stirring my weights using only basic back-prop and dumb simple loss mechanisms like a bunch of idiots, I'm not going to find smarter ways to do any of this without a shitton of weight stirring'

[@geekswithfeet9137]

This….. you are completely right, it’s a function of the efficiency of simple feedback. It has a noise floor constantly rescrambling the weights with every operation, there’s no gating or non-linear behaviour in the back-prop preventing “stirring” on irrelevant data. I truely believe the biggest jump we see in advancement will be better “neurons” not better models….. don’t get me wrong, better models will keep coming and get amazing….. but overnight the will ALL get better with better back-prop. Apply what we learned from non-linear forward prop, and use that to sieve the back-prop….. that step function in intelligence could rock out world in a matter of hours, because every model out there can suddenly use the same weights and go back into training and find a whole new level in hours

The guys actually thought that they made a major discovery about gravity... while literally being 40 years behind the tip of the spear.

Effectively, it is not believed whether increasingly massive computational capacity is the breakthrough needed to achieve AGI or even ASI.

This is definitely not an unavoidable physical limitation, considering that brains exist.

The missing piece of this puzzle probably lies in advancements in neuromorphic computing, and an adaptation of LLM architecture to take advantages of such hardware such as synaptic plasticity and saving efficiency by using analog computing for the weights.

Interesting. And yet, despite the incredible decrease in Validation Loss with model size, and compute, the model still gets an incredible number of things "wrong", which suggests, there is a fundamentally different issue happening as well.

[@NemisCassander]

Given that I believe LLMs are, at their core, statistical models, I'm not surprised at all that error on a training set decreases with the number of variables. It's been very well known that you can improve the 'fit' of a statistical model (from single regression all the way here) by increasing the number of variables. The risk is, of course, overfitting. That could be one source of tension in the models, that by increasing the variables, you improve on the training set but not its actual predictive capability. I understand that GPT-4's training set is, effectively, the Internet... but there may be an issue with the fact that people just... talk differently online. Which would be another source of error.

[@SMorales851]

If LLM Validation Loss works as described in the video, then what it is really measuring is the "believability" of the produced text. Low validation loss means the text is understandable and could have been conceivably written by a human. The correctness of the meaning conveyed by the text is a wholly different property, which is only indirectly captured by the LLM by virtue of the fact that most text written by humans (and thus the training data) is intended to convey correct information. Thus, for text to "look right" it at least has to "look correct". The LLM training optimizes for believability, and so the LLM makes mistakes very confidently and eloquently

[@personzorz]

They are not being trained with a reward function that has anything to do with the veracity of the output. It's just trained one token at a time. A very local, very greedy training.

[@altrag]

@@NemisCassander > That could be one source of tension in the models, that by increasing the variables, you improve on the training set but not its actual predictive capability. The real problem is that the models can't actually "understand" what you're asking. They're just pulling a statistically likely next word. It's why prompt writing has become a job title - it's not sufficient to askChatGPT a question and expect it to intuit your meaning, you have to ask it the question in a way that navigates around it's statistical model and avoids answers you don't want. Certainly having more context (ie: more training data and a longer input buffer) can help mask over that problem, but it never gets rid of it. That said, current AIs have so much training done that the problem is rarely it's intrinsic lack of understanding - more often than not the problem is that it's been trained on data from the internet, and the internet is pretty famously full of crap. It's the culmination of all knowledge, including vast amounts of "knowledge" that was invented out of whole cloth. Garbage in, garbage out.

You can teach them to embed themselves in low-level code or create abstraction layers (hypervisor rootkits in a sense), and they can stay in systems for a while. That's how you get to AGI in my view. It sounds scary but it does not need to be if they evolve in a more or less aligned manner. We already have a bunch of "bots" doing simple things on the internet. However, they lack the reasoning and generative power behind that powerful systems like o1-preview offer. The question is, is leaving a bunch of engineers and scientists and other people unemployed actually good for the economy? that can create other issues but I do not see those issues being "AI winters" or so. Thoughts?

They could be, if they’re used for research in that field

The earliest computers in the 1950s-1960s were exceptionally slow and used tons of power, yet they were essential to our computing journey. Of course, what we're doing right now is indeed worth it. We can't improve efficiency without starting somewhere.

I want AI to unlokc some real world challenges like assessing the damage to a vehicle after an accident based on pic taken by your phone

[@HexerPsy]

But why? The human at the repair shop takes into account a few key of data points: The cost of the parts The cost of labor How much you are willing to overpay. Each of these has its own subpoints, until it rolls out an estimate. The human mechanic should do better than just a picture of the damage and AI.

[@Little-bird-told-me]

@@HexerPsy All this can take many days and multiple visits. Imagine the whole process of insurance approval happening in a few clicks, and repair shops pick the vehicle, does their thing based on the inputs. Now, Imagine the driver is a lady. Unlocks many layers of complexity

Your NVIDIA V100 specs are wrong ( <a href="#" class="seekto" data-time="136">2:16</a> ). It’s 112 TFLOP/s fp16 with fp32 accumulate for the PCI-E card. The SXM2 card is 125 TFLOP/s. Eight V100s is 1 PetaFLOP/s. You are off by a factor of four because read the wrong number off the spec sheet.

Some of the craziest shit we've seen over the last few years is the ability to detect likeness between images. You can upload an image of something and computers can find similar images. If you upload a picture of a person, it can find other images of that same person even if it doesn't know who that person is (you uploaded an original picture). As this gets more powerful, the future will be a strange place none of us can predict.

nice explained with good animations simplify understanding the problem. thank you very much

Unfortunately, not all of us were financially literate early. I was 35 when I finally educated myself and started taking steps. I went from $176,000 in debt with zero savings or retirement to now, 2 years later, fully debt-free and over $1000,000 net worth. I know that doesn't SOUND like a lot, but I'm incredibly proud of it. Now I'm fast-tracking my wealth building (investing $400,000 annually) and don't owe a dime to anyone. It's a good feeling!

[@DevinWiebe]

Most people think, investing in crypto is all about buying coins and leaving it to rise, come on it takes much analysis to be a successful crypto trader.

[@FeliciaEmily-m2y]

Wow that's huge, how do you make that much monthly?

[@AmarachiSteve]

It really helped trading with michelle sule stewart analysis and info, even with the market in a downward trend. Definitely riding the market wave is a good perspective.

[@stoneJulio]

Thats true, I've been getting assisted by a Fx michelle for almost a year now, I started out with less than $200K and I'm just $19,000 short of half a million in profit.

[@ThomasJames-g2v]

Honestly speaking.... I will continue to trade / and stick to Michelle sule / daily analysis and guides as long as it works well for me.

[@m3rify]

Brilliant explanation! Really nailed it using names and concepts when they were needed to clutch it all together💕💘

[@BlowAway11]

Incredibly fantastic illustration! Subbed :)

LLMs are not thinking. They are just predicting and regurgitating. When we have real AI, wake me up.

[@randomuserame]

When "we" get it, it will already be a decades-old technology; and we will get it via a leak/whistleblower. The first "thinking machines" will be Military or claimed by militaries through the imminent domain clauses of their respective countries. _Then the end begins._

[@RIPPEDDRAGON40k]

Yeah but what if that is all we are doing too... just with more compute power currently...

[@meleardil]

They keep calling it AI. It is not. Opinion: It is a Virtual Intelligens mapping products of real intelligence. The dimension of LLM is the minimum meaningful pattern dimension of the used inputs. So basically it is the pattern storage dimension of human intelligence. That is also a reason of degradation. When VI is fed by its own products, you have a positive mismatch feedback. these VI's are not stable, because they are just imprints, and as such does not include the original control feedback of true AI.

@@RIPPEDDRAGON40k That is certainly not all that we do.
