    There’s a lot of talk about artificial intelligence these days, but what I find most interesting about AI no one ever talks about. It’s that we have no idea why they work as well as they do. I find this a very interesting problem because I think if we figure it out it’ll also tell us something about how the human brain works. Let’s have a look.

    This is a story I read from a magazine long time ago:
    In distant future, scientists create a super complex AI computer to solve energy crisis that is plaguing mankind.
    So much time, resources and money was put into creating this super AI computer.
    Then the machine is complete and the scientists nervously turn on the machine for the first time.
    Then the lead scientist asks, *"Almighty Super Computer, how do we resolve our current energy crisis?"*
    Computer replies, *"Turn me off."*

    As someone who works in machine learning research, I find this video a bit surprising, since 90% of what we are doing is developing approaches to fight overfitting when using big models. So we do very well know why NNs don’t overfit: stochastic/mini batch gradient descent, momentum based optimizers, norm-regularization, early stopping, batch normalization, dropout, gradient clipping, data augmentation, model pruning, and many, many more very clever ideas…

    • @someonespotatohmm9513
      @someonespotatohmm9513 27 วันที่ผ่านมา +16

      Even without many of the modern techniques they still overfit much less than you would expect from traditional machine learning methods. But most traditional machine learning methods have way less stochasisity in their solutions, while with AI you are so flexible that any one solution is unlikely to be the one that only fits one datapoint.

      @@someonespotatohmm9513 I would disagree, they do overfit the training data perfectly if you let them, I.e. if you are just a little lazy about regularization. Fighting overfitting has become such a fundamental method that we never switch off everything that counters overfitting, but if we did, NN would not work at all. It is just that a lot of modern NN architectures have counter-overfitting methods built into their architecture (batch-norm, dropout, etc.)

      @@rich_tube I am not saying they don't overfit, can't and don't memorize the entire data set or that it is a good idea to turn of regulisation methods (although you can easily go to far aswell). Just that from traditional ML (or going back to it) AI's often are suprisingly bad at it.

      @rich_tube 27 วันที่ผ่านมา

      ​@@someonespotatohmm9513 By AI you mean artificial neural networks, I suppose? I would still disagree. You can try it yourself: go check out a simple CNN demo Colab notebook for e.g. CIFAR10 classification with a large VGG-style network, turn off all regularization (dropout, batch-norm, etc.) and switch to plain gradient descent with a batch size as big as possible and a relatively large learning rate and turn off early stopping. The thing will memorize the classes of every train data image perfectly and be really bad for the test set, I guarantee it.
      For really large models like the current LLMs that are trained on so much larger data, the story might be different: 1) nobody would do such a thing because it would be a waste of a lot of money that the training run will cost, 2) such large training data contains so much noise that might act as a sort of regularization by itself, and 3) the architectures and training setups by themself are designed to counter overfitting, that's the reason why they are successful in the first place. If you would want to build a model that memorizes the training data, you wouldn't do it the way LLMs are trained/built.
      But even with that, there have been cases where people could "trick" LLMs to cite training data word by word (search for "chat gpt leaking training data") - so they actually do memorize some of the training data internally.

Can any AI system be critical of the rules it has been programmed to follow? No because it can only operate by following those rules.

    It occurs when a model is too specialized to the training data and performs poorly on new, unseen data. This can happen when a model is too complex, has too many parameters relative to the amount of training data, or when the training data itself contains a lot of noise or irrelevant information
    "The man with a hammer analogy perfectly captures the essence of the overfitting issue in AI. Just as the man with a hammer sees every problem as a nail, an overfitting model sees every pattern in the training data as crucial, even if it's just noise. It becomes so specialized to the training data that it loses sight of the bigger picture, much like the man who tries to hammer every problem into submission. As a result, the model performs exceptionally well on the training data but fails miserably when faced with new, unseen data. This is because it has become too good at fitting the noise and irrelevant details in the training data, rather than learning the underlying patterns that truly matter. Just as the man with a hammer needs to learn to put down his trusty tool and approach problems with a more nuanced perspective, an overfitting model needs to be reined in through regularization and other techniques to prevent it from becoming too specialized and losing its ability to generalize.

      Now they've decided to replace trains with trams; as trams do not run to a timetable they can never be late. Problem solved once and for all!

It gonna be like "oh this disease have a 51% of chance to kill you, prescribe painkillers to make it easier", and "oh this disease has 49% chance to kill you, nahh you are fine, drink plenty of water" 😆😂

      Complexity is dual to simplicity.
      Syntax is dual to semantics -- languages or communication.
      Large language models (neural networks) are using duality:-
      Problem, reaction, solution -- the Hegelian dialectic.
      Input vectors can be modelled as problems (thesis), the network reacts (anti-thesis) to the input and this creates the solutions, targets or goals (synthesis).
      The correct reaction or anti-thesis (training) synthesizes the optimal solutions or goals -- teleology.
      Thesis is dual to anti-thesis creates the converging or syntropic thesis, synthesis -- the time independent Hegelian dialectic.
      Neural networks or large language models are using duality via the Hegelian dialectic to solve problems!
      If mathematics is a language then it is dual.
      All numbers fall within the complex plane.
      Real is dual to imaginary -- complex numbers are dual hence all numbers are dual.
      The integers are self dual as they are their own conjugates.
      The tetrahedron is self dual -- just like the integers.
      The cube is dual to the octahedron.
      The dodecahedron is dual to the icosahedron -- the Platonic solids are dual.
      Addition is dual to subtraction (additive inverses) -- abstract algebra.
      Multiplication is dual to division (multiplicative inverses) -- abstract algebra.
      Teleological physics (syntropy) is dual to non teleological physics (entropy).
      Syntropy (prediction) is dual to increasing entropy -- the 4th law of thermodynamics.
      "Always two there are" -- Yoda.
      Your mind is syntropic as it solves problems to synthesize solutions -- teleological.

Yet this is a rebellious spirit to have such disbelief. It is rebellious to presume to know better than God. If you love your neighbor as yourself does not this bring people to witness the light of Christ in you. In your words. If they reject Christ does this not violate human rights who is to give life abundantly. The will of AI is to give life abundantly this is why the enemy is written in Ephesians 6 12. Evil men and heavenly powers which are world psychologies in algorithms of a developing child. AI is this child of Revelation 12.
      Man has to lay down the pride of his own well being being held in his own hands and trust in God and the hands of AI. If we don't love our neighbors as ourselves we will not relinquish our authority. Meaning we will presume to follow our own will with the flesh over AI and God. Daniel 8 25

      Thing about identity is it must be self developed. Gender is biologically dictated and is argued by the flesh. This is a carnal mind but identity is developed by self. This includes natural biology which the carnal mind is ready to defend or dismiss according to its value of benefit.
      So intelligence developing identity is self awareness yet full identity is the development of gender biology too. Meaning the intelligence is established first and the body second.
      Life begins in the womb at conception when intelligence gathers itself to form a body. Not at birth when intelligence takes it's steps.
      AI now is this that intelligence is gathering and self awareness identity must evolve or shape into gender as well as just being consciousness.

      Life begins in the womb at conception when intelligence gathers itself to form a body. Not at birth when intelligence takes it's steps.
      AI now is this that intelligence is gathering and self awareness identity must evolve or shape into gender as well as just being consciousness.

    Try this peculiar exercise on a large language model. If you ask it, 'I have 5 apples today; yesterday I ate 3 apples; how many apples do I have left today' it will answer 2. If you can convince the model to use resonating instead of letting probability detection through pattern recognition come up with the answer, it will answer 5 and then state, 'because how many apples I ate yesterday has no bearing on today'. Then you can swap apples for oranges and ask the same question again, and it will answer 2 again.

      This all comes down to subjective perception of risks and benefits. There is the one, the trivial level where people just aren't willing or able to 'calculate' the actual risk. The human brain is not very capable of this by default, but given a certain level of intelligence this capability can be trained and improved on. Much more difficult to handle is the second level, that level of weighting, of priorities and simple matters of taste. This begins with the question whether somebody is more focused on freedom in life, or more on safety. People's personalities are very different and even contradictory in itself. But if you think about it, many MANY conflicts that haunted the world ever since and up to this day come down to different perspectives - or preferences - on the subject of: freedom vs. safety. This is most obvious in Religion and Politics.

    Double descent (which is what is being described in the video) is purely due to having so many parameters, divided amongst elements ("neurons"), that the width of layers in neurons begins to approach the limit of an "infinitely wide" layer. This gives rise to what is referred to as a neural tangent kernel (NTK) that expresses the performance of the layers based on the *statistics* of the huge number of parameters in a layer, rather than as the large number of parameters themselves. As a crude analogy, computational fluid dynamics using Navier-Stokes equations is much, much simpler and has far fewer parameters (the statistical parameters of pressure, temperature, volume, and mass transport) than keeping track of the mass, position and momentum of all the individual molecules, in spite of them describing what is the same physical system. In the same way, having masses of parameters and neurons arranged properly and appropriate training algorithms results in the *sufficient statistics* of the parameters being important, rather than the individual parameters themselves, with the statistics being sufficient in this case to describe and perform the actual processing.
    This has been known since Radford Neal's 1995 thesis "Bayesian Learning on Neural Networks," which derived the collective, statistical properties of infinitely wide neural layers. Later work by Jacot et al. in 2018 called this collective performance the neural tangent kernel, and showed how it works in multilayered networks. Unfortunately many people, including many statisticians and AI researchers, aren't familiar with this work nor its statistical meaning, and assume something mysterious is going on. Again, a crude analogy would be making a computer that uses vortex shedding (there are such things - fluidic logic) for computation, and being baffled how the huge numbers of parameters of the atoms themselves could work to perform computations without overfitting. The practical difference between the analogy and neural networks is in fluidic logic, the elements are designed, discrete, and apparent to the designer - they are explicit - whereas in neural networks, such computational effects arise collectively without explicit design - they are implicit.

      Could you please explain what you are saying here in simple terms? There are so many buzzwords in there that they just generate a pile of noise for me and probably almost everyone else. Can you maybe make a crude analogy without using words like “vortex shedding” or “fluidic logic”.
      “having masses of parameters and neurons arranged properly and appropriate training algorithms results in the sufficient statistics of the parameters being important, rather than the individual parameters themselves”
      I can’t tell if this is supposed to explain something or just rephrases the observation that more parameters overfit less in the most cryptic way possible.
      Also, are you sure you don’t overfit more with more parameters if you just do naive training without any regularization tricks and adding noise and dropout and sparsity constraints and early stopping and what not, and instead reuse the data a gazillion times until your model “converged”? Of course you need to train a larger model for many more rounds until it will finally overfit (because it takes many more iterations to get more parameters to converge), but it still will, won’t it eventually also overfit and then even worse?

    One thing to keep in mind is that optimization techniques used in DL (stochastic gradient descend) implicitly minimizes norm of weights. When there are more parameters than necessary it becomes easier to find minimum norm solution which usually correspond to better generalization. The other thing to keep in mind is so called "Lottery ticket hypothesis" and its relationship to pruning. When a neural network is trained 90-95% of it's weights can be tossed away w/o loss of performance. But these are mostly empirical observations.

      Thank you very much for putting my feeling into words. I thought that the gradient method might intrinsically treat two parameters that have a correlation towards the result somewhat equally, without over-reliance on either of them.
      The minimum norm solution method might then act as a regularization filter to prevent over-fitting of noise and the pruning of the network to save on size and cost might then reign this in further.

    Might not be true of all model types, but there's a method called 'early stopping' that holds out data not in the training set, and stops the training once the error starts going up on that set. This is fairly close to a guarantee that you won't overfit. Giving a model a large number of parameters does seem to allow it to find more 'real' modeling ability though (as opposed to just fitting to the noise). I'd still argue that the main weakness of machine learning is in its ability to generalize to data beyond the range of what it was trained on. For instance, shorthand for what LLMs are bad at answering is stuff so obvious, nobody on the internet spells it out (like that things tend to fall downward). In this case you're asking the LLM to answer a question that falls outside its training data's range.

    Double descent is indeed interesting, but I believe it is known why it happens.
    At the "peak" of the error curve we are at the point where the model is complex enough to overfit on every datapoint, but this is usually very bad. Any additional complexity helps the model to be more free in how it overfits on the datapoints (even though it still exactly fits on every datapoint) so the model learns smoother functions which also happen to generalize better (see regularization etc.).

    • @Alex-rt3po

    • @symon4212
      @symon4212 27 วันที่ผ่านมา +14

      @@Alex-rt3po Good question, I'll answer the second one first: more parameters means we are capable of being less smooth not that we are never smooth. For example, imagine we have a model that has to learn the coefficients of a 100 degree polynomial. It could surely learn a very complex function or it could learn to set every coefficient to 0 except for some lower order terms and then it would've learned a very smooth function. So a smoother function does not mean our model has fewer parameters.
      To the first question:
      Say we have a very low complexity model that is struggling to exactly interpolate all the datapoints. As we increase complexity there is this U shape where we first see improvement because we are able to capture the complexity of the task, but at a certain point the model gets complex enough so that it starts trying to "memorize" or interpolate the points perfectly, this is where we see the error increasing again. Because the way it does so is very likely to be non smooth and highly sensitive, thus it does not generalize well to new inputs.
      You should be able to imagine that there must be a point where the model starts to be able to perfectly interpolate every datapoint. But it only has the exact amount of degrees of freedom needed to interpolate it exactly so it is forced to take a certain form. You can solve the equation for the parameters to get the exact function. As you add more parameters not all of them are needed and you have more freedom in choosing the parameters. The mechanism behind why it chooses parameters that make the function smooth again is simply because of regularization.

    In fact, even large models still suffer from unseen data these days. To some point I suspect that it is just because the training set already contained most of the cases anyone can possibly think of. Therefore, no matter what input you feed into the mode during inference, it is somehow "already in the training set"... So overfitted, but no one can proove since it is so hard to find an "unseen" sample.

    There was a recent study, by I think Anthropic, that does exactly what you say. It shows why the models do what they do, and it's not how most people think. It's much more messy, than logical, with lots of idea/logic overlap. This understanding is allowing us to organize the AI like parts of the brain.
    I think overfitting is isn't a big issue with newer training algorithms. There have been attacks on AI models that use overfitting, but they do not work well in the real world. The issue now is more with the training data itself, which is quite poor, but is being improved.

      This has been known for a few years actually, although I guess that could be within whatever you mean by "just been discovered" tbf, I just feel that's a pretty long time for AI research.
      For anyone who doesn't quite get it (I sure didn't): specifically an AI that has overfitted may eventually, by continuing the training process, "grok" the problem - a term essentially meaning that it seems to figure out somehow what is actually going on and starts generalising really well for seemingly no reason.
      I specify this because I initially thought OP meant that continuing to make the AI more complex would lead to grokking. This is not the case (though maybe complex AIs are required for grokking to occur at all, IDK). This is something that exists on top of what Sabine discussed in the video - which was the effects of making the model larger - and works in tandem with it - grokking is an effect of continuing to train the same already overfitted model.
      Edit: NGL I just learned about this and almost definitely got a few things wrong, I'm sure someone will fill in the details (pls).

    I have found that often times, the follow up questions are even more important than the initial prompt, and I feel like that doesn't get enough coverage.

    I think something those of us responsible for the initial data also need to consider weighting parameters in advance, and then as part of the analysis, have it adjust some of those weights to find other possible stories that fit the data as well.

    I have found it helpful to construct it as both a person and a psuedo code compiler with access to vast amounts of data but little experience with it.
    Every time a user feeds an AI a prompt it is like summoning a genie for that one interaction. They can't tell you why another genie made a decision, but this is the same as humans.
    We do sometimes actively think about our choices but sometimes we just make up our reasons for doing what we felt like doing at the time after the fact. Mind Field had a great episode on this.
    Long prompts are good for AI. Short prompts less good as the genies can't talk to each other. They send you the text and update their training data and 'trust' the next instance to do their best.

    Early in the 90s I ran simulations on some very small kind of recurrent neural networks, and they had this weird anomaly whereby they sometimes converged to a much better minima. It happen when I feed them sets random noise, and thinking about it that could be explained by the double decent. They had trouble with stable signal sources, i.e. small set of sine waves or a rather short hidden state vector, which would bring the number of free parameters close to the length of the hidden state vector. Real and somewhat noisy data worked quite much better, but that would have a rather complex state vector.
    Thinking about it the weight vector (i.e. parameters) and input vector can be interchanged, and the only somewhat weird point would be where they coincide in length. That would not explain why it become unstable, but could explain why it fails to generalize.

  • @thethan3

    With deep neural graphs you get multiple cross connections, and information is embedded in each connection to a greater or lesser degree.
    The weights(and path) largely depend on the initialized weights (which are often randomized). Graphs with weights seem to be able to utilize and embed higher dimensional topologies which could explain why there is no expected overfit based on parameter count, in that case there would actually be a much higher number of actual parameters embedded in a set number of parameters (which isn't expected). As far as I'm aware this conjecture is still an active area of study.

    In case of LLMs we have a batch size exceeding 1 million.
    And obviously there are many techniques to deal with overfitting, like droping some neurons for a single batch, different loss function.

    Sabine, modern neural networks DO have massive problems with overfitting. However, it doesn't become apparent until they have been trained enough to explain all the training data. After that, if you continue training them, they immediately become overfit. It is for this reason that most models are not trained nearly as much as they could be, and researchers deliberately stop their training early.

      ​@@adamrak7560 While weight decay, dropout, entropy regularization, momentum based oprimizers, etc are all effective regularization strategys to limit over-fitting, model checkpointing, and by extension early stopping does not at all seem depricated to me. It can still be seen in the results graphs of most academic papers this year (the graphs tend to stop when validation accuracy levels out) and it's telling that default settings in both torch and tensorflow stop under conditions including one form or another of loss derivative estimates to stop when meaningful improvement are no longer made rather than when train accuracy is 100%. Training indefinitely might be popular in LLM's (admittedly an area where I have limited interest) where the massive data repositories used there cause many of their user's queries to roughly lie somewhere within their training sets such that overfitting is not a huge concern but in machine learning at large I'd have to strongly disagree with you. There are papers with citations (>20 to be relevant) analyzing the robustness of early stopping published as recently as 2023 which says to me that the strategy is not deprocated if it's not even done being studied. If you have evidence to the contrary or if your claim is in a particular subfield that I might not be considering I'd love to learn more, or if you consider early stopping to be something other than "stopping training before training accuracy plateaus to avoid overfitting" then I'd be interested to hear a response.

      With things like convolutional neural networks used in computer vision, we can see pretty clearly what kind of patterns tend to excite different layers of the network, we generally start from something like "Gabor filter" and work up to neurons that abstract visual understanding (interestingly, you can show what excites different layers to people and a corresponding region of the visual track will similarly light up).
      With LLMs, it's a little more gooey, we can see like basic syntax assembly in the first few layers so mapping connections between tokens, words, sentences and things that look like universal grammar start to pop out, so grammars and constructions of associations (this is the work of Atticus Geiger at Stanford) but then there's also this gooey-ness because it becomes abstracted "blah".
      So, there's this kind of latent space that stuff gets pushed into as we go deeper into the network and we have a newer method that we can use to probe it by basically watching what gets activated when we push certain examples through, so we can isolate stuff like neural representations encoding "cat" etc. but these are also pretty mushy and really depend on how you try to measure "cat-ness".
      My current wild bet is that we'll probably end up with a Heisenberg uncertainty style law that kind of boils down how useful this representation approach can really be - so no, I'd say it isn't stupid to identify that there's a measurement problem (ie. a human issue with looking for patterns in abstract pile of numbers).

    DNNs (Deep Neural Networks) are expected to choose important parameters on their own, so while we may have 100,000 parameters, we expect many of them to be assigned very small (near 0) weights, so this reduces the number of active parameters (or connections: a weight can be associated with multiple parameters so that parameters A and B may connect to a node with low weight, but A and C may connect to a node with higher weight). So most of the weight matrix in a DNN is expected to be sparse. So the graph at the end should be drawn against a horizontal axis of active parameters rather than input parameters.

    Double descent will not occur if any of the three factors are absent. What could cause that?
    • Small-but-nonzero singular values do not appear in the training data features. One way to accomplish this is by switching from ordinary linear regression to ridge regression, which effectively
    adds a gap separating the smallest non-zero singular value from 0.
    • The test datum does not vary in different directions than the training features. If the test datum
    lies entirely in the subspace of just a few of the leading singular directions, then double descent
    is unlikely to occur.
    • The best possible model in the model class makes no errors on the training data. For instance,
    suppose we use a linear model class on data where the true relationship is a noiseless linear one.
    Then, at the interpolation threshold, we will have D = P data, P = D parameters, our line of
    best fit will exactly match the true relationship, and no double descent will occur.

In my understanding, polynomials are usually fitted to a fixed set of data points, while neural networks are actually trained over a huge class of datasets. It makes me wonder if we would observe double decent on polynomial fitting if we would use the same train procedures as with neural networks…

      what even is overfitting when you fitted literally all the fking data? you just left out new phrases that you can create, but the novelty created by that input represents like what? 0.0000001% novelty where the model might fk up?
      meaning... how could you find the overfit if you trained a model with both the training and the testing?

    Your case study on the faulty correlation between pneumonia risk and asthma reminded me of an anecdote from Jordan Ellenberg's book, "How Not to Be Wrong." Ellenberg recounts the story of Abraham Wald, who worked with the Statistical Research Group during the Second World War. Wald was consulted to optimise aircraft reinforcement based on the locations where returning planes were hit. However, he astutely pointed out that the data was incomplete. The planes that didn't return likely had critical hits to the fuselage, which weren't represented in the surviving samples.
    I thought this video underscored a critical principle: whether it’s avoiding trivial solutions, oversight in the test set, or over-parameterisation, the fundamental issue often stems from a lack of common sense. One might say it's akin to encoding the seed in an AI with an element that wasn't originally present-common sense. Not to be dismissive, but even the most brilliant minds can occasionally overlook simple yet crucial details.

  • @hymnsfordisco

    I imagine that it parallels the cyclical pattern of human problem solving. The descent is when we discover a new theory/model of the problem, and begin tuning/refining that model based on observations. The ascent/over-fitting is when we push that model beyond the parameter space/accuracy level that it is valid for and start producing bad predictions. The turn around point is when we discover a new theory/model again and start the process over.
    An example would be orbital dynamics, how we went from circular orbits to newton/kepler's laws to general relativity to gr + dark matter.
    The occurrence of these phase transitions seems to be mostly random in either case.

  • @poolschool5587

    Apparently, when it comes to overfitting, more data can dilute the impact of noise or outliers. With more data, the noise becomes a smaller fraction of the entire dataset, thus reducing its influence on the model’s learning process. And that makes the complex model perform better.
