Opinions on Interpretable Machine Learning and 70 Summaries of Recent Papers

This is extremely cool -- thank you, Peter and Owen! I haven't read most of it yet, let alone the papers, but I have high hopes that this will be a useful resource for me.

Against GDP as a metric for timelines and takeoff speeds

Thanks for the post! FWIW, I found this quote particularly useful:

Well, on my reading of history, that means that all sorts of crazy things will be happening, analogous to the colonialist conquests and their accompanying reshaping of the world economy, before GWP growth noticeably accelerates!

The fact that it showed up right before an eye-catching image probably helped :)

Debate update: Obfuscated arguments problem

This may be out-of-scope for the writeup, but I would love to get more detail on how this might be an important problem for IDA.

Debate update: Obfuscated arguments problem

Thanks for the writeup! This google doc (linked near "raised this general problem" above) appears to be private: https://docs.google.com/document/u/1/d/1vJhrol4t4OwDLK8R8jLjZb8pbUg85ELWlgjBqcoS6gs/edit

Verification and Transparency

This seems like a useful lens -- thanks for taking the time to post it!

Understanding Iterated Distillation and Amplification: Claims and Oversight

I do agree. I think the main reason to stick with "robustness" or "reliability" is that that's how the problems of "my model doesn't generalize well / is subject to adversarial examples / didn't really hit the training target outside the training data" are referred to in ML, and it gives a bad impression when people rename problems. I'm definitely most in favor of giving a new name like "hitting the target" if we think the problem we care about is different in a substantial way (which could definitely happen going forward!)

Understanding Iterated Distillation and Amplification: Claims and Oversight

OK -- if it looks like the delay will be super long, we can certainly ask him how he'd be OK w/ us circulating / attributing those ideas. In the meantime, there are pretty standard norms about unpublished work that's been shared for comments, and I think it makes sense to stick to them.

Understanding Iterated Distillation and Amplification: Claims and Oversight

I agree re: terminology, but probably further discussion of unpublished docs should just wait until they're published.

Understanding Iterated Distillation and Amplification: Claims and Oversight

Thanks for writing this, Will! I think it's a good + clear explanation, and "high/low-bandwidth oversight" seems like a useful pair of labels.

I've recently found it useful to think about two kind-of-separate aspects of alignment (I think I first saw these clearly separated by Dario in an unpublished Google Doc):

1. "target": can we define what we mean by "good behavior" in a way that seems in-principle learnable, ignoring the difficulty of learning reliably / generalizing well / being secure? E.g. in RL, this would be the Bellman equation or recursive definition of the Q-function. The basic issue here is that it's super unclear what it means to "do what the human wants, but scale up capabilities far beyond the human's".

2. "hitting the target": given a target, can we learn it in a way that generalizes "well"? This problem is very close to the reliability / security problem a lot of ML folks are thinking about, though our emphasis and methods might be somewhat different. Ideally our learning method would be very reliable, but the critical thing is that we should be very unlikely to learn a policy that is powerfully optimizing for some other target (malign failure / daemon). E.g. inclusive genetic fitness is a fine target, but the learning method got humans instead -- oops.

I've largely been optimistic about IDA because it looks like a really good step forward for our understanding of problem 1 (in particular because it takes a very different angle from CIRL-like methods that try to learn some internal values-ish function by observing human actions). 2 wasn't really on my radar before (maybe because problem 1 was so open / daunting / obviously critical); now it seems like a huge deal to me, largely thanks to Paul, Wei Dai, some unpublished Dario stuff, and more recently some MIRI conversations.

Current state:

  • I do think problem 2 is super-worrying for IDA, and probably for all ML-ish approaches to alignment? If there are arguments that different approaches are better on problem 2, I'd love to see them. Problem 2 seems like the most likely reason right now that we'll later be saying "uh, we can't make aligned AI, time to get really persuasive to the rest of the world that AI is very difficult to use safely".
  • I'm optimistic about people sometimes choosing only problem 1 or problem 2 to focus on with a particular piece of work -- it seems like "solve both problems in one shot" is too high a bar for any one piece of work. It's most obvious that you can choose to work on problem 2 and set aside problem 1 temporarily -- a ton of ML people are doing this productively -- but I also think it's possible and probably useful to sometimes say "let's map out the space of possible solutions to problem 1, and maybe propose a family of new ones, w/o diving super deep on problem 2 for now."
