I intuit that what you mentioned as a feature might also be a bug. I think that practical forgetting/unlearning that might make us safer would probably involve subjects of expertise like biotech. And if so, then we would want benchmarks that measure a method's ability to forget/unlearn just the things key to that domain and nothing else. For example, if a method succeeds in unlearning biotech but makes the target LM also unlearn math and physics, then we should be concerned about that, and we probably want benchmarks to help us quantify that.
I could imagine an unlearning benchmark, for example, with $n$ textbooks and $n$ ap tests. Then for each of $k$ different knowledge-recovery strategies, one could construct the $n \times n$ grid of how well the model performs on each target test for each unlearning textbook.
+1, I'll add this and credit you.
Several people seem to be coming to similar conclusions recently (e.g., this recent post).
I'll add that I have as well and wrote a sequence about it :)
I think this is very exciting, and I'll look forward to seeing how it goes!
Thanks, we will consider adding each of these. We appreciate that you took a look and took the time to help suggest these!
No, I don't think the core advantages of transparency are really unique to RLHF, but in the paper, we list certain things that are specific to RLHF which we think should be disclosed. Thanks.
Sounds right, but the problem seems to be semantic. If understanding is taken to mean a human's comprehension, then I think this is perfectly right. But since the method is mechanistic, it seems difficult nonetheless.
Thanks -- I agree that this seems like an approach worth doing. I think that at CHAI and/or Redwood there is a little bit of work at least related to this, but don't quote me on that. In general, it seems like if you have a model and then a smaller distilled/otherwise-compressed version of it, there is a lot you can do with them from an alignment perspective. I am not sure how much work has been done in the anomaly detection literature that involves distillation/compression.
I think this is a good point, thanks.
We talked about this over DMs, but I'll post a quick reply for the rest of the world. Thanks for the comment.
A lot of how this is interpreted depends on what the exact definition of superposition that one uses and whether it applies to entire networks or single layers. But a key thing I want to highlight is that if a layer represents a certain set amount of information about an example, then they layer must have more information per neuron if it's thin than if it's wide. And that is the point I think that the Huang paper helps to make. The fact that deep and thin networks tend to be more robust suggests that representing information more densely w.r.t. neurons in a layer does not make these networks less robust than wide shallow nets.
