How does it work to optimize for realistic goals in physical environments of which you yourself are a part? E.g. humans and robots in the real world, and not humans and AIs playing video games in virtual worlds where the player not part of the environment. The authors claim we don't actually have a good theoretical understanding of this and explore four specific ways that we don't understand this process.
The apparent successes of the deep learning revolution conceal a dark underbelly. It may seem that we now know how to get computers to (say) check whether a photo is of a bird, but this façade of seemingly good performance is belied by the existence of adversarial examples—specially prepared data that looks ordinary to humans, but is seen radically differently by machine learning models.
The differentiable nature of neural networks, which make them possible to be trained at all, are also responsible for their downfall at the hands of an adversary. Deep learning models are fit using stochastic gradient descent (SGD) to approximate the function between expected inputs and outputs. Given an input, an expected output, and a loss function (which measures "how bad" it...
Do you know if it is happening naturally from increased scale, or only correlated with scale (people are intentionally trying to correct the "misalignment" between ML and humans of shape vs texture bias by changing aspects of the ML system like its training and architecture, and simultaneously increasing scale)? I somewhat suspect the latter due the existence of a benchmark that the paper seems to target ("humans are at 96% shape / 4% texture bias and ViT-22B-384 achieves a previously unseen 87% shape bias / 13% texture bias").
In either case, it seems kind...
Hypothesis, super weakly held and based on anecdote:
One big difference between US national security policy people and AI safety people is that the "grieving the possibility that we might all die" moment happened, on average, more years ago for the national security policy person than the AI safety person.
This is (even more weakly held) because the national security field has existed for longer, so many participants literally had the "oh, what happens if we get nuked by Russia" moment in their careers in the Literal 1980s...
Produced while being an affiliate at PIBBSS[1]. The work was done initially with funding from a Lightspeed Grant, and then continued while at PIBBSS. Work done in collaboration with @Paul Riechers, @Lucas Teixeira, @Alexander Gietelink Oldenziel, and Sarah Marzen. Paul was a MATS scholar during some portion of this work. Thanks to Paul, Lucas, Alexander, Sarah, and @Guillaume Corlouer for suggestions on this writeup.
What computational structure are we building into LLMs when we train them on next-token prediction? In this post we present evidence that this structure is given by the meta-dynamics of belief updating over hidden states of the data-generating process. We'll explain exactly what this means in the post. We are excited by these results because
I am trying to wrap my head around the high-level implications of this statement. I can come up with two interpretations:
Yes, thanks!
If we achieve AGI-level performance using an LLM-like approach, the training hardware will be capable of running ~1,000,000s concurrent instances of the model.
Although there is some debate about the definition of compute overhang, I believe that the AI Impacts definition matches the original use, and I prefer it: "enough computing hardware to run many powerful AI systems already exists by the time the software to run such systems is developed". A large compute overhang leads to additional risk due to faster takeoff.
I use the types of superintelligence defined in Bostrom's Superintelligence book (summary here).
I use the definition of AGI in this Metaculus question. The adversarial Turing test portion of the definition is not very relevant to this post.
Due to practical reasons, the compute requirements for training LLMs...
I think this only holds if fine tunes are composable, which as far as I can tell they aren't
You know 'finetunes are composable', because a finetune is just a gradient descent step on a batch of data and a parameter update, and if you train on more than one GPU and share updates, DL training still works {{citation needed}}.
If you can train asynchronously on a thousand, or 20,000, or 100,000 GPUs, that is what you are doing; this is especially true in DRL, where you might be, say, training across 170,000 CPU-cores. (You are certainly not accumulating the ...
Abstract:
Inspired by the Kolmogorov-Arnold representation theorem, we propose Kolmogorov-Arnold Networks (KANs) as promising alternatives to Multi-Layer Perceptrons (MLPs). While MLPs have fixed activation functions on nodes ("neurons"), KANs have learnable activation functions on edges ("weights"). KANs have no linear weights at all -- every weight parameter is replaced by a univariate function parametrized as a spline. We show that this seemingly simple change makes KANs outperform MLPs in terms of accuracy and interpretability. For accuracy, much smaller KANs can achieve comparable or better accuracy than much larger MLPs in data fitting and PDE solving. Theoretically and empirically, KANs possess faster neural scaling laws than MLPs. For interpretability, KANs can be intuitively visualized and can easily interact with human users. Through two examples in mathematics and physics, KANs are shown to be useful collaborators helping scientists (re)discover mathematical and physical laws. In summary, KANs are promising alternatives for MLPs, opening opportunities for further improving today's deep learning models which rely heavily on MLPs.
(likely conditional on some aspects of the training setup, idk, self-supervised predictive loss function?)
Pretraining, specifically: https://gwern.net/doc/reinforcement-learning/meta-learning/continual-learning/index#scialom-et-al-2022-section
The intuition is that after pretraining, models can map new data into very efficient low-dimensional latents and have tons of free space / unused parameters. So you can easily prune them, but also easily specialize them with LoRA (because the sparsity is automatic, just learned) or just regular online SGD.
But yeah,...
Q. "Can you hold the door?" A. "Sure."
That's straightforward.
Q. "Can you play the violin at my wedding next year?" A. "Sure."
Colloquial language would imply not only am I willing and able to do this, I already know how to play the violin. Sometimes, what I want to answer is that I don't know how to play the violin, I'm willing to learn, but you should know I currently don't know.
Which I can say, it just takes more words.
If you're working at the intersection between cryptogrpahy, secuity and AI, consider joining this upcoming workshop:
Foresight's AGI: Cryptography, Security & Multipolar Scenarios Workshop
May 14-15, all-day
The Institute, Salesforce Tower, San Francisco
Goals
To help AI development benefit humanity, Foresight Institute has held various workshops over the past years and launched a Grants Program that funds work on AI security risks, cryptography tools for safe AI, and safe multipolar AI scenarios. Our 2024 workshop invites leading researchers, entrepreneurs, and funders in this growing space to explore new tools and architectures that help humans and AIs cooperate securely. In addition to short presentations, working groups, and project development, we offer mentorship hours, open breakouts, and speaker & sponsor gatherings.
Questions we’ll address include
I'll be there! Talk to me about boundaries and coordination/Goodness
There's also the problem of: what do you mean by "the human"? If you make an empowerment calculus that works for humans who are atomic & ideal agents, it probably breaks once you get a superintelligence who can likely mind-hack you into yourself valuing only power. It never forces you to abstain from giving up power, since if you're perfectly capable of making different decisions, but you just don't.
Another problem, which I like to think of as the "control panel of the universe" problem, is where the AI gives you the "control panel of the universe", bu...
