Recent advances in large language models (LLMs) have centered around more data, larger models, and larger context lengths. The ability of LLMs to learn in-context (i.e. in-context learning) makes longer context lengths extremely valuable. However, there are some problems with relying on just in-context learning to learn during inference.

The points you bring up about the failures of RAG and incontext learning are more broadly problematic. I've frequently wondered why LLMs fail to be able to "synthesize" information from different sources. Try to get an LLM to debate you on a topic. it's completely futile because the LLM just regurgitates information from its training data (with all its associated biases). It doesn't do any reading between the lines, by taking disparate sources of information and having that "Eurika" moment when two, at first, disconnected ideas come together to introduce new knowledge. In essence, LLMs are still just context dependent pattern recognition machines.

After you first brought up continual learning versus long context / RAG, I immediately think of the example of just asking for advice from customer service staff with a manual, versus asking a technician. RAG is like a CS person that could quickly find the page related to your question. In context seems a bit better, the person had read the manual and probably can bring you a bit insight, depends on how smart that person is. But continual learning, ideally means the manual is fully understood by the person. They learnt it, instead of remembering it. Ideally, depends on how good a learner they are.

I paused. From my experience working in production with RAG... simply it's like using a legacy technology to fill in the blanks in training. Attention mechanisms are way more subtle and nuanced than semantic search lookup.... if there was a cheap way to viably do continual learning in a production environment, and still allow context windows, etc. it would solve the whole problem of semantic search not being enough to find the right data you really need.

I agree, RAG feels very empty to me. Like, once you intelligently find the relevent text for a prompt in your vector db, it seems like the LLM isn't really even needed anymore. Why not just use the vector search and ranking by itself at that point? To me, the value of the LLM is its ability to create new content, and RAG basically puts the LLM in a tiny box.

This is also my thinking If you can find the right documents anyway, that means the documents (and the answer) already exists and you don't need the LLM to read it and essentially play it back to you. IF you can find the right documents that is. Therefore we either focus on finding the right documents or we continually train the LLMs -> how are you doing that?

Remember back when we were first learning about grammar, parts of speech, and literary devices? Perhaps an LLM can be used alongside a classroom of children and learn all these finer nuances in the same way. Of course, I think it is also worth recognizing that we create from our experiences. The way we felt at the park on that one special day, when the cool summer breeze was gently blowing across our skin. Would the lack of physical/emotional experience always detract from the quality of a poem? Perhaps it would only succeed in the creation of a more cryptic form of poetry... like, "The Red Wheelbarrow" which lacks technical correctness entirely yet is still a poem of quality.

lets be honest, documentation generally sucks. I'm an open source contributor and the biggest issue users report is "your docs suck". RAG doesn't solve out-of-distribution situations, so it's not a magic bullet. Even when developers try to write good docs, it quickly becomes out of date and wrong. until we have better architectures, continuous training will be needed.

I am not convinced by your arguments. In my work, I often need to tell business people that we should not do training or fine-tuning until we see that in-context learning is not enough. And in the end, it turns out that in-context learning is enough, even for those complicated examples you described. Let me argue with your arguments. 1. `Where does the context come from?` - Well, if we have no context then any training is even more out of the question than in-context learning, right? I don't see how that would be an argument for continual learning. 1.1 `RAG won't enable our models to solve complicated or niche problems` - It can. If LLM is capable enough and has great general knowledge then it can often solve problems that no human has ever solved before, just using its general knowledge and some additional context about the problem that needs solving. 2. `The scope of in-context learning is limited by pertaining data` - agreed. However, the most capable models are trained on almost every type of data you can imagine. That means that you probably won't find a problem for which in-context learning won't work for those models. This can however be a problem if you are working with less capable, smaller models. For me the biggest problem of RAGs is that models do not work well with very large contexts. Even if you have 128k context length in gpt4, it won't be able to reason well with 100k tokens of table data or system logs or even a codebase. Instead, it will often "misread" or "forget" information in such a long context. That's more of a limitation of current LLMs, I think, not an intrinsic characteristic of RAG systems.

These are some great points, and there is a large hole in my video because I left out half of the argument for brevity. The most crucial point I think is the question of where the context comes from, because of course, you aren't going to get any benefits of continual learning if you have nothing to learn from 😛 The answer to this is having RL agents generate their own data via experience. The thing about this approach is that it requires you to continually get new data that is more related to what you want to solve. But if you aren't continually learning, you won't be able to generate continually more relevant data (unless it happens to fit into your context window). For smaller problems this is often not a problem, but what if you want to learn an entirely new programming language or learn calculus? You can't just give a bit of context; you have to learn from a continually changing curriculum as you learn one topic after the other. That is where this approach makes sense. This is why I agree with you to an extent on point 1.1. If there is a problem just on the boundary of what humans haven't done before, RAG + in-context learning can potentially solve it. But if you want to build on that new knowledge, and then build on that, and build on that, and so on, that is where you need continual learning, and these are the types of problems that researchers and startups often face. They are problems that require layers of learning. That being said, I disagree with point 2. There are sooo many things these agent are not trained on, but they do require you going deep into specific domains most of the time. The long context is one problem I was originally going to bring up in the video, but I decided against it because models will keep getting better at dealing with longer context as training methods and architectures improve. These other problems will not go away. I appreciate the well thought out critique

@@EdanMeyeragreed, I also would like to bring up the point that context size brings O(n^2) scaling. So with a massive context window, you will eventually hit a point where training becomes just as cheap as a few forward passes. Also even with a nearly unlimited, yet finite, context size, you will eventually run out of room for very specific tasks like working with a code base long term. Then training on that knowledge becomes a very viable option because it would essentially reset the ctx window size. Also LLMs perform worse on larger contexts windows, and that is just a given, they will always perform worse with larger windows of info because humans also have the same flaw, and LLMs are trained to mimic human writing, so having a smaller window will always yield better performance

But, I am glad someone is working on the problem now so that we can transfer over when the time comes. Humans continual learn so it only makes sense for our AI models to do the same. Data is the future and ways to generate useful data will be key.

And regarding creative and smart combination solutions for (new) tasks, without really good prompting leading the LLM nothing happens in that direction.

@@li_tsz_fung that depends on the training method and optimizer plus if it starts to overfit, but there is a secret little thing I learned with diffusion models that might be useful, if you merge the model with a tiny percentage of "random weights" as you keep training, it keeps 'destroy' some of the previously contained information, while training afterwards will kinda re-heal the whole thing. It prevents overfitting quite well, bc usually overfitting is when it starts to develop TOOOOO strong patterns, but tiny percentages of random weights disrupts that and also helps get it out of any "local maxima" it might get stuck on. local maxima: imagine it as a possible 'hole' where the training is leading the model state into, but its not the most optimal one, it just feels like its optimal for the training algorithm due to the insane multidimensional nature of that many matrices being multiplied together.

The main reason we dont do CL is nbecause there is nothing in old fashioned CL that actually works. Currently the only thing that learns from the previous and improves is in context learning. Yes we need continual learning but it should be by making incontext learning lighter. More fundamentally, we need to separate between memory based incontext continual learning and parameter continual learning. The former is to add up event based knowledge while the latter is to add up intrincsic reasoning capabilities. The former should be based on external memory while the latter is on the parameter level. Right now we have the former in the name of incontext learning using token memory. The community is already doing research along this direction although not in the name of CL.

You can use the llm to decide what information is relevant, by adding an extra call to the database. For example the llm can output 75 keywords that request the context needed. Then that gets sent to the llm again, allowing for nearly 100% correct context. Along with the possibility of the LLM being allowed to make 5-10 context calls back to the database. You overcome these issues.

Great video! I totally agree about the potential downsides about RAG. There's another issue with RAG and in context learning, namely that current LLMs often are good at retrieval when given a long context ("needle in a haystack") but not good very good at connecting the dots and reasoning about what's in the context. But about your example where context is missing, I think continually learning is also not really helping. If you don't have data for context, then you probably also don't have it for learning in most circumstances. It seems a more general problem for which the solution would be to have a LLM that is better at reasoning and generalizing

Yes! You got it! I left out half of the argument for brevity, but you also need to be able to get the data to do continual learning. The solution there is to have an agent generate its own data via experience (i.e. RL). The thing is that you can't generate experiences that are continually more relevant to what you want to learn unless you are continually learning. Hence, both of these systems are essential as a pair.

As we know, you can be an expert in some fields, but quite unlikely in many fields. On the other hand, we could leverage our "learning" ability to solve any problem, given the learning materials. Intuitively, this "learning ability" sounds fundamentally different than weights updating of a LLM fine-tuning, where we use this ability to learn knowledge. From this point of view, we might still be far from the "General AI".

VERY interesting! A few questions, if I may: 1. Do you use LoRA? 2. Does your LLM operate with a level of certainty of the data it produces? Can it detect a paradox or an absurd in its own answer? Can it do so prior to the final output? 3. Do you consider self-improving LLMs? Let me explain. Obviously, a static LLM represents a set of frozen-in-time (not-so-simple) links between an input and an output. The quality of those outputs is directly linked to the number of different data points and vectors connecting them (and to the precision of those vectors). So, the question is -- is it possible for an LLM to scan those vectors, extract patterns and then apply them to other areas to get extra data where the density of data is lower? Something like DLSS does with images, you know?

if we think of LLMs as brain-esque (which is not necessarily true, but they are somewhat similar), we can think of RAG as just telling you how everything works. showing you the docs, showing you examples, etc. Could you write good code quickly after just seeing examples and docs? maybe, but it gets much easier after practice. practicing stuff literally changes how our neurons connect to make certain connections more likely than before. This is analogical to changing the weights on the LLM. Instead of just trying to remember what they were given in the docs - which is somewhat problematic, their weights are literally changed to make them better at this specific task - like how our brains literally change when we practice things.

Great points. I agree…partially. I def believe in lifelong learning styles of training. I say partially because I see inherit rigid flexibility. First off, what data mixing is being used? You didn’t mention this at all. Whenever we continually train, you notice spikes in loss, this is due to the an anticipatory behavior of these models on past representation. So this means we need to contextually sample small portions of pretraining data and mix with new data, along with some DAP-based method. Careful learning rate tuning. We can greatly mitigate catastrophic forgetting. Ain’t no way this isn’t abdunant in your setup? How do you approach this? Also long context ICL has it faults but I feel long-term it will outshine raw tuning. Think batchicl or many-shot ICL with LM generated interleaved rationales. Any limitation you mentioned can be optimized. Pretraining or continual pretraining with a joint Lm(compiled NN, maybe even great latent variables for the LM to represent different states to trigger diff types of symbolic programs in our compiled NN) and system-2 attenion(reformulate to append a linearized KG after context refinement)… I still believe in long context ICL..long-term. Great content though. Especially if the LM is equipped with symbolic logic..obviously it would have profound impacts on generalization, assuming your pretraining data is augmented with this style of hybrid data. You literally need a LM to process all training data I believe for this to really work(not changing, adding to the sample context. You must retain the original entropy or…model collapse 😂). At least this the first principle my startup is building from.

I mean I feel like extremely long contexts, and a model that can actually utilise this context to a good degree of accuracy, is essentially continuous learning in a way lol. But also you do have some good points. And this reminds me of what Andrej Karpathy said about how pretty much no current models are truly open source. If you wanted a truly open source model you would not only open source the weights but also the training sets for example, and having access to these training sets allows you to do things like continued pretraining (as you also mentioned training with a mix of the old and new does well in mitigating catastrophic forgetting, and im pretty sure that's how OAI has been updating the knowledge cutoff in their models). Ive never seen RAG as like a long term solution as it just doesn't allow the model to capture the things it would via continued pretraining or ICL. Having that extra context it can build up an intuition of sorts on the information you have given it which I think will be much more advantageous and its overall just more flexible. And for continuous learning maybe you could update only a subset of the model, the relevant weights? This would be a lot cheaper and CF wouldn't be as prevalent, and those spikes in the loss should also not be as dramatic because you are updating the weights that are more relevant to the new data, it might also lead to reduced overfitting because your not allowing the entire model to adjust to the new dataset. But this solution does present its own challenges.

@@DanielSeacrest great points bro. Facts super long context and proper context utilization(most part, a data fallacy) is essentially active learning, since attention perturbs activated neurons. I seen some cool research where they backprop at test time against a constraint to “look in the future”, all that and things like quiet-star…I see a clear pathway for removing the need of fine tuning for MOST use cases. Yea that makes sense, given a training corpus, identify the most relevant subnetworks and freeze the rest. Wonder how we account for polysemantic nature of models though. Literature time lol. Saying this out loud, it seems so obvious. Has to be a paper already ha.

One approach is to implement continual learning gradually; you could use recently finished projects to train the model and eventually evolve to real-time continual learning. Yes, I understand you would like a problem-solving prediction based on inference from other experiences. You are asking the model to predict solutions based on abstract patterns that don't exist. Models already do that in the form of hallucinations.

Ofcourse we need AI systems with continual learning that has been whole vision of AI for years but we have to figure out a new architecture with existing LLM as we everytime we fine tune the system on new semantics the model weights are shifted towards new distribution and this leads to forgetting of previously learned information which disrupts the whole paradigm.

I seem to recall continual learning was essential to the Alberta Plan. in evolution, though, it seems more discrete. for example, all embryonic development converges to the homeobox gene clusters, which suggests distillation of more general biology to a more conservative genetic load. in other words, the information is offloaded to the environment determining how the system builds up or expresses itself. relating this to code generation, I think one of the key components is symbolically filtering for sequences of "atomic" programming (at the ahead-of-time level) that maintain the overall flow of fulfilling whatever niche consumers choose. ideally, at some point we elect for succinctness of verifiable programming & the core model is reflecting on the environment & either interpolating the agency it's already provably demonstrated or extrapolating novel agency that is provably the product of so many atomic programs within the environment.

When chatgpt arrived, it was like a wave, but it turns out that another novelty-driven convergence bias (getting caught up in the enthusiasm of a new idea and devoting all of your energy to making it even better, without evaluating alternative choices or thinking outside the box). As a non-coder who has been following the llm space for the past 6 months, I have realised that it is too long a journey to have a smart brain that will learn and process to execute; it is just a large language model, which implies constricting all data into a model, making it difficult to continuously fine-tune or train. Limitations in Neuro-Symbolic AI include the integration of structured knowledge representations, adaptability, abstract thinking, and reasoning. Emotional Intelligence and Creativity were the main reasons I suspended my interest in llm. I had plenty of creative ideas. One example: I extracted thousands of lyrics to create a model that will creatively construct a song and existing lyrics into a knowledge graph, but it was only a half-finished copy-paste job; the process of delving deeper into each lyrics that I input was much more difficult to implement. Now, I only use chatgpt or local llms for grammar correction and basic information.😅

The comments section here are gold 🙌🏾💜 My 2c: Both CL and RAG are vital. RAG provides the closest to real-time context and CL ensures the base model can appropriately interpret the context and meet output requirements. We're still very early in this latest season of AI solutions. I think arguing which is best isnt the most productive use of cognitive resources. It depends entirely on the application usecase. Some applications should absolutely be fine-tuning their own CL systems. But the vast majority can be handled with RAG. This is the allure and popularity of RAG. It's the tool thats cheap, accessible, and will get you pretty far most of the time. Unless you're an experimental quantum physicist or something then you'll surely need to finetune your own. With better data engineering for RAG systems I'm confident both points you described can be resolved within 6-18 months. Plenty of work to do till then 😁

In the event of pursuing research in the realm of "Theoretical Physics" or any theory-based research that prolongs for decades and decades before a theory is debunked... or until a new theory arises, what effect would that have on a Large Language Model applied to these areas? Having an LLM trained on theories that in the end may prove false would create a "hyper-intelligent" LLM built on incorrect data... would it not? Is this an area of research that allows for the application of LLM's? If so, to what extent? Perhaps this is not an area of research an LLM would even be trained on. I am in no way educated on the subject, but this video did immediately bring to mind those questions. I think continual learning may prove successful only in the event we are continually learning in a direction that leads to a "correct" conclusion.

My guesses: - A lot of code is undocumented, or documented too differently to generalize learning from it - Code doesn't just differ from language to language or library to library, but on a per project basis. - Specs change over time - The bigger the context, the more difficult it is to draw out the correct information - More context makes it generate slower or have more error.

The problem seems a bit more obvious if you consider the limits. If you have no base model, the in-context learning won't work. If you have a base model but more knowledge than fits in your context, in-context learning won't work. At some point, you are obligated to improve the base model to get results, so it's a bad premise to aim for a solution where you aren't training base models in any level. Great video, nice style!

I do not see this as a LLM or an ML problem. Even humans will struggle to learn and apply something new if they do not have a prior knowledge for it. For example an engineer will struggle with accounting or medicine . Coming back to LLM even with a context provided (RAG) if there was no prior knowledge existed in the training LLM will not produce the desired output. As stated before this is not a unique LLM problem , it s a gereral problem common with humans and machines.

Adding the relevant info to context is useful if the model already understands the context. If it doesn't, it must learn by changing the weights. From a neuroscience perspective, activities that rely on muscle memory cannot be learnt with the context approach, even if you are a genius. But you could learn calculus in one go with no sleep if smart and motivated enough. I imagine in robotics this will be similar, controllers based on transformers will need to be finetuned to the actuators, you can't provide context and just expect a pretrained model to follow the logical steps to adapt it's outputs to the new configuration. Thus must incorate dinamical learning, like humans do. It must somehow process the new info it learned during the day/session, build a training set from it and rehearse. I just hope they don't get demotivated in the journey like I do hahahah

I have to question whether LLMs - even in their most advanced form - are even plausibly capable of doing what you've declared your goal to be (generating brand new ideas that have never been thought of before). LLMs are prediction engines, and in order to predict, they learn from the past. How can one predict what has never happened, strictly from learning from the past? You might be able to predict that something new will happen, but never what that would be. I su[ppose that could be interesting in it's own right; the combination of factors X, Y, and Z results in a hole in the LLM's prediction. _Humans_ are pretty terrible at this task. Rarely does anyone have a truly new idea. Most of what feels like new is just recycled bits and pieces of old, reassembled into a different whole.

This is interesting, but I wonder if you're overestimating the difference between state of the art LLM's training data and the majority of research problems and incomplete libraries. Most research in scientific domains doesn't require a complete departure from previous work, and most incomplete libraries are not so alien from existing libraries that their intended functionality can't be understood by an LLM. Granted, even GPT4 by itself probably won't be enough to do really novel work, but GPT4 + LangChain or AutoGPT shows a lot of promise resolving some of the defects of LLMs, like their limited ability to reason. Food for thought ¯\_(ツ)_/¯ Anyway great video! Subscribed and looking forward to seeing where this goes.
