I think this test can be performed now or soon, but I'm not sure I'd update much from it. Current LMs are already pretty good at answering questions about themselves when prompted with a small amount of information about themselves. ("You are a transformer language model trained by AICo with data up to 2022/04"). We could also bake in this information through fine-tuning. They won't be able to tell you how many layers they have without being told, but we humans can't determine our brain architecture through introspection either.
I think the answer to "are you phenomenally conscious" will be sensitive to small differences in the training data involving similar conversations. Dialog-prompted models probably fall back on literary depictions of AI for self-oriented questions they don't know how to answer, so the answer might depend on which sci-fi AI the model is role-playing. (It's harder to say what determines the OOD behavior for models trained with more sophisticated methods like RLHF.)
Re: smooth vs bumpy capabilities, I agree that capabilities sometimes emerge abruptly and unexpectedly. Still, iterative deployment with gradually increasing stakes is much safer than deploying a model to do something totally unprecedented and high-stakes. There are multiple ways to make deployment more conservative and gradual. (E.g., incrementally increase the amount of work the AI is allowed to do without close supervision, incrementally increase the amount of KL-divergence between the new policy and a known-to-be-safe policy.)
Re: ontological collapse, there are definitely some tricky issues here, but the problem might not be so bad with the current paradigm, where you start with a pretrained model (which doesn't really have goals and isn't good at long-horizon control), and fine-tune it (which makes it better at goal-directed behavior). In this case, most of the concepts are learned during the pretraining phase, not the fine-tuning phase where it learns goal-directed behavior.
To do what, exactly, in this nice iterated fashion, before Facebook AI Research destroys the world six months later? What is the weak pivotal act that you can perform so safely?
Do alignment & safety research, set up regulatory bodies and monitoring systems.
When the rater is flawed, cranking up the power to NP levels blows up the P part of the system.
Not sure exactly what this means. I'm claiming that you can make raters less flawed, for example, by decomposing the rating task, and providing model-generated critiques that help with their rating. Also, as models get more sample efficient, you can rely more on highly skilled and vetted raters.
Found this to be an interesting list of challenges, but I disagree with a few points. (Not trying to be comprehensive here, just a few thoughts after the first read-through.)
IMO prosaic alignment techniques (say, around improving supervision quality through RRM & debate type methods) are highly underrated by the ML research community, even if you ignore x-risk and just optimize for near-term usefulness and intellectual interestingness. I think this is due to a combination of (1) they haven't been marketed well to the ML community, (2) lack of benchmarks and datasets, (3) need to use human subjects in experiments, (4) it takes a decent amount of compute, which was out of reach, perhaps until recently.
Weight-sharing makes deception much harder.
Could you explain or provide a reference for this?
I'm especially interested in the analogy between AI alignment and democracy. (I guess this goes under "Social Structures and Institutions".) Democracy is supposed to align a superhuman entity with the will of the people, but there are a lot of failures, closely analogous to well-known AI alignment issues:
I think it's more likely that insights will transfer from the field of AI alignment to the field of government design than vice versa. Easier to do experiments on the AI side, and clearer thinkers.
Would you say Learning to Summarize is an example of this? https://arxiv.org/abs/2009.01325
It's model based RL because you're optimizing against the model of the human (ie the reward model). And there are some results at the end on test-time search.
Or do you have something else in mind?
Thanks, this is very insightful. BTW, I think your paper is excellent!
I'm still not sure how to reconcile your results with the fact that the participants in the procgen contest ended up winning with modifications of our PPO/PPG baselines, rather than Q-learning and other value-based algorithms, whereas your paper suggests that Q-learning performs much better. The contest used 8M timesteps + 200 levels. I assume that your "QL" baseline is pretty similar to widespread DQN implementations.
Are there implementation level changes that dramatically improve performance of your QL implementation?
(Currently on vacation and I read your paper briefly while traveling, but I may very well have missed something.)
