Edit: contest closed now, will start assessing the entries.
The contest
I'm offering $1,000 for good questions to ask of AI Oracles. Good questions are those that are safe and useful: that allows us to get information out of the Oracle without increasing risk.
To enter, put your suggestion in the comments below. The contest ends at the end[1] of the 31st of August, 2019.
Oracles
A perennial suggestion for a safe AI design is the Oracle AI: an AI confined to a sandbox of some sort, that interacts with the world only by answering questions.
This is, of course, not safe in general; an Oracle AI can influence the world through the contents of its answers, allowing it to potentially escape the sandbox.
Two of the safest designs seem to be the counterfactual Oracle, and the low bandwidth Oracle. These are detailed here, here, and here, but in short:
- A counterfactual Oracle is one whose objective function (or reward, or loss function) is only non-trivial in worlds where its answer is not seen by humans. Hence it has no motivation to manipulate humans through its answer.
- A low bandwidth Oracle is one that must select its answers off a relatively small list. Though this answer is a self-confirming prediction, the negative effects and potential for manipulation is restricted because there are only a few possible answers available.
Note that both of these Oracles are designed to be episodic (they are run for single episodes, get their rewards by the end of that episode, aren't asked further questions before the episode ends, and are only motivated to best perform on that one episode), to avoid incentives to longer term manipulation.
Getting useful answers
The counterfactual and low bandwidth Oracles are safer than unrestricted Oracles, but this safety comes at a price. The price is that we can no longer "ask" the Oracle any question we feel like, and we certainly can't have long discussions to clarify terms and so on. For the counterfactual Oracle, the answer might not even mean anything real to us - it's about another world, that we don't inhabit.
Despite this, its possible to get a surprising amount of good work out of these designs. To give one example, suppose we want to fund various one of a million projects on AI safety, but are unsure which one would perform better. We can't directly ask either Oracle, but there are indirect ways of getting advice:
- We could ask the low bandwidth Oracle which team A we should fund; we then choose a team B at random, and reward the Oracle if, at the end of a year, we judge A to have performed better than B.
- The counterfactual Oracle can answer a similar question, indirectly. We commit that, if we don't see its answer, we will select team A and team B at random and fund them for year, and compare their performance at the end of the year. We then ask for which team A[2] it expects to most consistently outperform any team B.
Both these answers get around some of the restrictions by deferring to the judgement of our future or counterfactual selves, averaged across many randomised universes.
But can we do better? Can we do more?
Your better questions
This is the purpose of this contest: for you to propose ways of using either Oracle design to get the most safe-but-useful work.
So I'm offering $1,000 for interesting new questions we can ask of these Oracles. Of this:
- $350 for the best question to ask a counterfactual Oracle.
- $350 for the best question to ask a low bandwidth Oracle.
- $300 to be distributed as I see fit among the non-winning entries; I'll be mainly looking for innovative and interesting ideas that don't quite work.
Exceptional rewards go to those who open up a whole new category of useful questions.
Questions and criteria
Put your suggested questions in the comment below. Because of the illusion of transparency, it is better to explain more rather than less (within reason).
Comments that are submissions must be on their separate comment threads, start with "Submission", and you must specify which Oracle design you are submitting for. You may submit as many as you want; I will still delete them if I judge them to be spam. Anyone can comment on any submission. I may choose to ask for clarifications on your design; you may also choose to edit the submission to add clarifications (label these as edits).
It may be useful for you to include details of the physical setup, what the Oracle is trying to maximise/minimise/predict and what the counterfactual behaviour of the Oracle users humans are assumed to be (in the counterfactual Oracle setup). Explanations as to how your design is safe or useful could be helpful, unless it's obvious. Some short examples can be found here.
EDIT after seeing some of the answers: decide on the length of each episode, and how the outcome is calculated. The Oracle is run once an episode only (and other Oracles can't generally be used on the same problem; if you want to run multiple Oracles, you have to justify why this would work), and has to get objective/loss/reward by the end of that episode, which therefore has to be estimated in some way at that point.
A note on timezones: as long as it's still the 31 of August, anywhere in the world, your submission will be counted. ↩︎
These kind of conditional questions can be answered by a counterfactual Oracle, see the paper here for more details. ↩︎
Submission: Low-bandwidth oracle. Here is a description of one million experiments. Generate an ordinal ranking of all these experiments based on how much practical knowledge we would have gained had we conducted each one in isolation. After you generate this list, it will go to a computer program. This program will randomly pick three of these experiments and tell us humans which three it picked. This program will then store which of these three experiments you gave the highest and which the lowest rank to, and the names in random order of the ten experiments that you overall gave the highest rankings to. All other aspects of your list will be deleted. We will then perform the three experiments (before we learn of your rankings) and ask a panel of independent experts to rank them in terms of how much practical knowledge we gained from each. After this ranking the program will give us the information it has not deleted. You will get a positive score if and only if your ranking is consistent with how our experts ranked the three experiments.
A difference of the above approach compared to having the oracle give us its top ten, and we then randomly pick one of these ten and one from the rest and compared to see which is better is that the humans running the experiments might be influenced by which experiment they think the oracle picked, and the oracle would take this into account when picking. Under the above approach, humans being told to run the three experiments are not given any information about how valuable the oracle thinks the experiments are. In contrast, under the alternative approach the humans know when doing the experiments that the oracle has judged one of the experiments as being highly valuable.
Another difference is that if you could keep the relevant information from the oracle, with the above approach the humans could perform the experiments before you turn on the oracle, rather than having to wait until after the oracle gives you its prediction. This difference would be critical if the oracle wouldn't believe you would actually go to the trouble of performing the experiments after it gives you its prediction, but would be able to tell if you have already performed the experiments.
