Go and Chess still has rules that are hard coded which at least gives a framework to optimize in. What rules do you give an LLM?

Physics.

I'm skeptical of the idea that anything is going to derive intelligence from the bottom up, but I'll be super impressed if that's how it goes.

> I guess people working there believe in magic. I've been thinking about this recently. Personally, I've yet to see any compelling evidence that an LLM, let alone any AI, can operate really well "out of distribution". It's capabilities (in my experience) seem to be spanned by the data it's trained on. Hence, this supposed property that it can "train itself", generating new knowledge in the process, is yet to be prov…

The question is not whether it can work right now, but whether it is possible in the future (i.e. whether it's possible in principle). I think the concern about out-of-distribution is overstated. If we train it on predicting machine learning papers, writing machine learning papers is not out-of-distribution. You might say "but writing NOVEL papers" would be OOD; but there's no sharp boundary between old and new. Mode…

Interesting, I suppose what you're proposing is that models could, in some abstract way, extrapolate research results taking ideas A and B that it "knows" from its training, and using them to create idea AB. Then, we assert that there is some "validation system" that can be used to validate said result, thus creating a new data point, which can be retrained on.

I can see how such a pipeline can exist. I can imagine the problematic bit being the "validation system". In closed systems like mathematics, the proof can be checked with our current understanding of mathematics. However, I wonder if all systems have such a property. If, in some sense, you need to know the underlying distribution to check that a new data point is in said distribution, the system described above cannot find new knowledge without already knowing everything.

Moreover, if we did have such a perfect "validation system", I suppose the only thing the ML models are buying us is a more effective search of candidates, right? (e.g., we could also just brute force such a "validation system" to find new results).

Feel free to ignore my navel-gazing; it's fascinating to discuss these things.

Perhaps doing this to generate 10 similar but different versions of a model can then be fed into mixture of experts?

Ooh that’s a good idea! Although mistral seems to have been seeded with identical copies of mistral, so maybe it doesn’t buy you much? Sounds worth trying though!

The deep problem of my life: I'm interested in so many things, but only have time to pursue one hobby and one neuroscience career. If it is indeed a good idea, its only from connecting gleaned generalizations with other gleaned generalizations; but the devil is often in the details; and I will never have enough time to try myself. :)

Am i missing something, or is this just a case of "amortized inference", where you train a model (here a diffusion one), to infer something that was previously found via optimization procedure? (here NN parameters).

I don't claim it's impossible, just that there isn't a clear path from what exists now to that reality, and that the explanation presented by the above commenter (and I suppose OpenAI's website) does not clarify what they think the path is

We can reason about it without knowing the path. E.g. somebody in 1950s could say "If you have enough compute you can do photorealistic quality computer graphics". If you ask them how to build a GPU they won't know. Their statement is about principal possibility.

Yes, and there are lots of predictions about when that would happen that turned out to be very wrong. Even if there is a clear path and specific people assigned to do a thing, it is famously always more difficult than expected for those people to correctly estimate how long it will take. Forgive me for being skeptical of random laypeople giving me timelines for an unknown unknown based on an objective that is ill-specified for work being done on something for which there is currently a lot of marketing hype

I wasn't sure if this paper was parody on reading the abstract. It's not parody. Two things stand out to me: first is the idea of distilling these networks down into a smaller latent space, and then mucking around with that. That's interesting, and cross-sections a bunch of interesting topics like interpretability, compression, training, over- and under-.. The second is that they show the diffusion models don't just…

Hmmm, I could think of using it to update a DDPM with a conditioning input as the dataset expands from an RL/online process, without ruining the conditioning mechanism that's only trainable through the actual RL itself.

I.e., self-supervised training is done to produce semantically sensical results, and the RL-trained conditioning input steers to contextually useful results.

(Btw., if anyone has tips on how to not wreck the RL training's effort when updating the base model with the recently encountered semantically-valid training samples that can be used self-supervised, please tell. I'd hate to throw away the RL effort expended to aquire that much taking data for good self-supervised operation. It's already looking fairly expensive...)

I think people can read books (self improvement) and have children (recursive), but neither of those are both.

Why do you think that the human population is more intelligent, knowledgeable, and achieves greater technological feats as time goes on? It's because of recursive self-improvement, we are raised and educated into being better in a quite general sense, which includes being better at raising and educating; nearly every generation this cycle repeats and has for all of human history, at least since we acquired language.…

You're pointing out that groups/institutions/cultures/civilizations are examples of recursively self-improving entities, but the original point was about a recursively self-improving individual intelligent entity.

Well, to the extent that a human-level intelligence is an individual, anyway. We ourselves are probably a mixture-of-experts in some sense.

Why not? We started off as single celled organisms and look at where we are now.

An individual human starts out a mewling baby and can end up a maxillofacial surgeon through at least partial examples of recursive self-improvement. Learn to walk, talk, read, write, structure, argue, essay, study, cite etc all the way through to the end, with what you previously learned allowing you to learn even more. There's a huge amount of outside help, but at least some of it is also self-improvement.

Also, for the purposes of talking about the phenomenon of recursive self-improvement, individual vs society isn't the end of analysis. Part of the reason AI recursive self-improvement is concerning is that people are worried about it happening on much faster than societal timescales, in ways that are not socially tractable like human societies are (e.g. if our society is "improving" in a way we don't like, we or other humans can intervene to prevent, alter, or mitigate it). It's also important to note that when we're talking about "recursive self-improvement" when it comes to AI, the "self" is not a single software artifact like Llama-70B. The "self" is AI in general, and the most common proposed mechanism is that an AI is better than us at designing and building AIs, and the resulting AI it makes us even better at designing and building AIs.
