Love pieces that manage to be both funny and thought-provoking. And +1 for fitting a solar storm in there. There is now better evidence of very large historical solar storms than there had been during David Roodman's Open Phil review in late 2014, have been meaning to write something up about that but other things have taken priority.

I have a writeup on solar storm risk here that could be of interest

This is cool, although I suspect that you'd get something similar from even very simple models that aren't necessarily "modelling the world" in any deep sense, simply due to first and second order statistical associations between nearby place names. See e.g. https://onlinelibrary.wiley.com/doi/pdfdirect/10.1111/j.1551-6709.2008.01003.x , https://escholarship.org/uc/item/2g6976kg .

Yes, people have been pulling this sort of semantic knowledge out of word embeddings since the start. Here is a long list from like 5 years ago, going far beyond just geographic locations: https://gwern.net/gpt-2#fn11

This is one of the reasons that people have rejected the claims that LLMs are doing anything special: because after all, just a word2vec, which barely even counts as a neural net, or n-grams, seems able to 'learn' a lot of the same things as a LLM does, even though it's "obviously" not a world model. (It's a modus ponens/tollens thing.)

Nice job! I'm working on something similar.

> Next, I might get my agent to attempt the last three tasks in the report

I wanted to clarify one thing: Are you building custom prompts for the different tasks? If so, I'd be curious to know how much effort you put into these (I'm generally curious how much of your agent's ability to complete more tasks might be due to task-specific prompting, vs. the use of WebDriverIO and other affordances of your scaffolding). If not, isn't getting the agent to attempt the last three tasks as simple as copy-pasting the task instructions from the ARC Evals task specs linked in the report, and completing the associated setup instructions? 

2Thomas Broadley
Thank you! No, I'm not building custom prompts for the different tasks. I wrote a single prompt template -- the only difference between runs is the task description, which gets plugged into the template. I think ARC Evals did the same thing. I have been improving the prompt as I worked through the tasks. I probably spent 2-3 hours working on the prompt to try and improve the agent's performance on some tasks. I'll definitely rerun all the tasks with the current version of my prompt, just to check that it can still perform the easier tasks. You're right that getting the agent to attempt the last three tasks is relatively simple. Still, I was thinking that it wasn't worth the time or money. I think it's very unlikely that the agent will succeed at any of the last three tasks. Still, maybe it's worth getting a conclusive negative result.

I'd recommend participating in AGISF. Completely online/virtual, a pretty light commitment (I'd describe it more as a reading group than a course personally), cohorts are typically run by AI alignment researchers or people who are quite well-versed in the field, and you'll be added to a Slack group which is pretty large and active and a reasonable way to try to get feedback.

It looks like their coursework has already started, but I have contacted the organizer. Thanks!

This is great. One nuance: This implies that behavioral RL fine-tuning evals are strictly less robust than behavioral I.I.D. fine-tuning evals, and that as such they would only be used for tasks that you know how to evaluate but not generate. But it seems to me that there are circumstances in which the RL-based evals could be more robust at testing capabilities, namely in cases where it's hard for a model to complete a task by the same means that humans tend to complete it, but where RL can find a shortcut that allows it to complete the task in another way... (read more)

4evhub
Yes, that's right. In some sense they're evaluating different capabilities—both "can a model find a way to do this task" and "can a model do what humans do on this task" are separate capabilities, and which one you're more interested in might vary depending on why you care about the capability evaluation. In many cases, "can a model do this task the way humans do it" might be more useful, since e.g. you might care a lot if the model is capable enough to replicate complex human labor, but not really care at all if the model can find some weird hack.

Nice, thanks for this!

If you want to norm this for your own demographic, you can get a very crude estimate by entering your demographic information in this calculator, dividing your risk of hospitalization by 3 and multiplying the total by 0.4 (which includes the 20% reduction from vaccination and the 50% reduction from Paxlovid)

Anecdotally, I feel like I've heard a number of instances of folks with what pretty clearly seemed to be long Covid coming on despite not having required hospitalization? And in this UK survey of "Estimated number of people (in tho... (read more)

I agree you can get long covid without hospitalization, but do think a demographic's chances of long covid scale with chance of hospitalization, roughly linearly, and hospitalization data is much easier to get. 

Irving's team's terminology has been "behavioural alignment" for the green box - https://arxiv.org/pdf/2103.14659.pdf

The byte-pair encoding is probably hurting it somewhat here; forcing it to unpack it will likely help. Try using this as a one-shot prompt:
 


How many Xs are there in "KJXKKLJKLJKXXKLJXKJL"? 

Numbering the letters in the string, we have: 1 K, 2 J, 3 X, 4 K, 5 K, 6 L, 7 J, 8 K, 9 L, 10 J, 11 K, 12 X, 13 X, 14 K, 15 L, 16 J, 17 X, 18 K, 19 J, 20 L. There are Xs at positions 3, 12, 13, and 17. So there are 4 Xs in total.

That's just BPEs, and it's worth noting that the other models (and by 'other', I do not mean "Stable Diffusion" like a lazy person would, I mean actual SOTAs) are much more capable of following long intricate prompts eg. Parti. What's going on with ChatGPT is also likely due to BPEs (as has been the case with GPT when asked to do letter-related tasks going back to GPT-2, as I have been repeating for years) plus perhaps some RLHF shenanigans. (RLHF seems to increase accuracy but sometimes greatly worsen results. I'm not yet sure why, but I suspect there may be something pathological in what RLHF rewards, where it is unable to do inner-monologue and incentivized to immediately jump to an answer.)

It seems like you're claiming something along the lines of "absolute power corrupts absolutely" ... that every set of values that could reasonably be described as "human values" to which an AI could be aligned -- your current values, your CEV, [insert especially empathetic, kind, etc. person here]'s current values, their CEV, etc. -- would endorse subjecting huge numbers of beings to astronomical levels of suffering, if the person with that value system had the power to do so.

What about pigs? You know the trillions of sentient beings as smart as four years that feel the same emotions as four year olds and are tortured and killed on a regular basis?

I'm not sure it makes sense to talk about what somebody's values are in the absence of social pressure: people's values are defined and shaped by those around them.

I'm also not convinced that every horrible thing people have ever done to the "outgroup" is motivated by fear.

This reminded me of some findings associated with "latent semantic analysis", an old-school information retrieval technique. You build a big matrix where each unique term in a corpus (excluding a stoplist of extremely frequent terms) is assigned to a row, each document is assigned to a column, and each cell holds the number of times that term  appeared in document  , and with some kind of weighting scheme that downweights frequent terms), and you take the SVD.

Why do you expect Bitcoin to be excepted from being labelled a security along with the rest? 
(Apologies if the answer is obvious to those who know more about the subject than me, am just genuinely curious)

4TropicalFruit
No, it's not obvious; it's a perfectly legitimate question. Here's the Howie test, the criteria established by the Supreme Court for security classification: 1. An investment of money 2. In a common enterprise 3. A reasonable expectation of profit 4. Derived from the efforts of others Bitcoin's biggest difference from other Crypto securities are #2 and #4. Bitcoin is common, but it's not exactly an "enterprise." There's no organization or group working on it in an attempt to increase it's value, the way, for example, the Ethereum foundation attempts to increase the economic value of ETH. There are the core devs, but the authority they have to actually change the software is much, much lower, requiring massive agreement across the board from miners and nodes. And for #4, while it is the miners efforts that create security for the network, it's not as direct as the members of other crypto projects actively working, for profit, on the software. The profit comes from Bitcoin's increasing network of users who decide to store their economic value in it, not because it's becoming a more and more useful piece of software as people improve it (like, say, what happens in a traditional equity like google or microsoft). Even still, it's certainly murky. Gary Gensler has stated Bitcoin alone is a commodity a few times: https://www.coindesk.com/layer2/2022/06/28/secs-gensler-reiterates-bitcoin-alone-is-a-commodity-is-he-right/ The main thing... Who exactly would be required to register Bitcoin with the SEC? Who would file the S1 disclosure with Bitcoin? Who would the SEC sue if "Bitcoin" was an unregistered security?  There was no IPO (well, ICO I guess). There's no foundation. There are no stakeholders; since Bitcoin is PoW.

Had a similar medical bill story from when I was a poor student: Medical center told me that insurance would cover an operation.

It's worth knowing that there are some categories of data that Surge is not well positioned to provide.

Thanks, I agree that's a better analogy. Though of course, it isn't necessary that none of the employees (participants in a sandwiching project) are unaware of the CEO's (sandwiching project overseer's) goal; I was only highlighting that they need not necessarily be aware of it in order to make it clear that the goals of the human helpers/judges aren't especially relevant to what sandwiching, debate, etc. is really about.

We start with some ML model which has lots from many different fields, like GPT-n. We also have a human who has a domain-specific problem to solve (like e.g. a coding problem, or a translation to another language) but lacks the relevant domain knowledge (e.g. coding skills, or language fluency). The problem, roughly speaking, is to get the ML model and the human to work as a team, and produce an outcome at-least-as-good as a human expert in the domain. In other words, we want to factorize the “expert knowledge” and the “having a use-case” parts of the prob

I at least partially buy this, but it seems pretty easy to update the human analogies to match what you're saying. Rather than analogizing to e.g. a product designer + software engineer, we'd analogize to the tech company CEO trying to build some kind of product assembly line which can reliably produce good apps without any of the employees knowing what the product is supposed to be. Which still seems like something for which there's already immense economic pressure, and we still generally can't do it well for most cognitive problems (although we can do it well for most manufacturing problems).

I just shared this info with an immune-compromised relative, thanks so much for this.

When I see young healthy people potentially obsessing, turning life into some sort of morbid probability matrix because one particular potential risk (Long Covid) has been made more salient and blameworthy, I sympathize a lot less. 

 

ONS's latest survey finds 2.8% of the UK population report that they are currently experiencing long COVID symptoms: 67% of that 2.8% report that the symptoms adversely affect their day-to-day activities. Separately, they've estimated that 70% of England has had COVID at least once; weighting their estimates for Engla... (read more)

The poster's concern is with long COVID, which can certainly have effects that a lot of people would consider severe. The "severe" COVID that has a baseline of less than 1% for the young and healthy refers to COVID that requires hospitalization. Long Covid rates are higher.

3pjeby
Also, some LWers are neither young nor healthy, and/or have family responsibilities that would become problematic or impossible at some levels of lasting lung or organ damage, whether you call it "long covid" or not. So I'm definitely waiting for more understanding of long-term effects before I change my risk profile.

I was slightly surprised to find that even fine-tuning GPT-Neo-125M  for a long time on many sequences of letters followed by spaces, followed by a colon, followed by the same sequence in reverse, was not enough to get it to pick up the pattern - probably because the positional encoding vectors make the difference between e.g. "18 tokens away" and "19 tokens away" a rather subtle difference. However, I then tried fine-tuning on a similar dataset with numbers in between (e.g. "1 W 2 O 3 R 4 D 5 S : 5 S 4 D 3 R 2 O 1 W") (or similar representation -- can't remember exactly, but something roughly like that) and it picked up the pattern right away. Data representation matters a lot!

Here's an example of someone prompting with a walkthrough of a similar token-aware approach to successfully guide GPT-3:

Thanks for sharing this! It is worrying, but the magnitude does not seem like it would change Zvi's overall conclusion. Some reasons why: * Not enormous increase in absolute terms. Per the article * Increase in stroke: 0.4% pts * Increase in HF: 1.2% pts * Most participants likely were not vaccinated (looking at the study itself) * 162,690 participants who had a positive COVID-19 test between 1 March 2020 and 15 January 2021 were selected into the COVID-19 group * Increase in any cardiovascular outcome for non-hospitalized individuals was 2.85% points (difference of 28.5 cases out of 1000) (Supplementary Table 8 in the study itself) * Stroke is 1.85 / 1000 (0.2% pts), heart failure is 6.05 / 1000 (0.6% pts) * I assume they highlighted stroke and HF because those are particularly severe issues, but eyeballing the table for other scary things (as someone who is not a medical expert): myocardial infarction 0.39, cardiac arrest -0.04, MACE (any major adverse cardiac events) 11.29 (all out of 1000) * Limitation with controls (though I dunno if this is likely to make a significant difference) * Ardehali cautions that the study’s observational nature comes with some limitations. For example, people in the contemporary control group weren’t tested for COVID-19, so it’s possible that some of them actually had mild infections. And because the authors considered only VA patients — a group that’s predominantly white and male — their results might not translate to all populations.

The way that data set is presented is infuriating – there are tables that list raw counts without reference to the sample size (maybe it’s an estimated raw number for the whole country, in which case they’re quite small)

Easy to miss but it's in thousands -- scroll to the far right of each table with raw numbers and you'll see that stated near the top.

In terms of hedons, many old people live in retirement homes under horrendous conditions. Some lose their marbles, I remember one who every day tried to escape while claiming "I have to take care of my goats!" Some forget that their loved ones are dead, only to relearn it and be sad again. Some have chronic pains. Some shit themselves because they can't control their sphincters anymore, then stay in their shit for hours while waiting for the single nurse who has 10 other residents to treat before them because the house is criminally understaffed. Their only joy besides the family's monthly visit is to eat shitty food and watch shitty TV. No, believe me, nobody would spend extra to provide better food for an elderly who might have lost their sense of taste and has no leverage anyway. There is something like negative hedons. There are things worse than death. Can we be real? The average year of an elderly doesn't have nearly as many hedons as the average year of a young adult.

Vaccinating to herd immunity proved impossible

The number of experiences I've had of reading an abstract and later finding that the results provided extraordinarily poor evidence for the claims (or alternatively, extraordinarily good evidence -- hard to predict what I will find if I haven't read anything by the authors before...) makes this system suspect. This seems partially conceded in the fictive dialogue ("You don't even have to dig into the methodology a lot") - but it helps to look at it at least a little. I knew a senior academic whose system was as follows: read the abstract (to see if the topic of the paper is of any interest at all) but don't believe any claims in it; then skim the methodology and results and update based on that. This makes a bit more sense to me.

(The preprint states: "In the 60+ group, we found lower risk of symptoms lasting for more than 28 days (OR=0.72, 95%CI [0.51-1.00])".)

Yeah, If I'm reading the preprint correctly, the effect is insignificant in the under 60 group, and the overall odds ratio (of long covid conditional on infection, I think) is basically 1 (Figure 3). I'm not sure if this is about the study being underpowered, or if there's just no effect.

Regarding the comments earlier in this thread suggesting that long Covid is largely misattributed depression, the symptom profile doesn't seem to bear this out. "At five weeks post-infection among Coronavirus Infection Survey respondents testing positive for COVID-19", quite a few are still experiencing symptoms that don't sound much like depression: 11% of individuals are still experiencing cough, 8% loss of taste, 8% loss of smell, 8% muscle pain.

No; my script only contains the handful of unicode characters I commonly use, and is so idiosyncratic to me that it wouldn't be of much use to anyone else (mine includes autoreplacements for directories, email addresses I commonly type, etc.). But it's easy enough to make your own with whatever characters you use -- the syntax is simply

etc.

I've taken the survey.

I keep a daily journal. Beginning of day: Two things that I'm grateful for. End of day: Two things that went well that day, two things that could have gone better. Each "thing" is usually only a sentence or few long. I find that going back through the end-of-day sentences every so often is useful for doing 80-20 analyses to find out what seems to be bringing me the most happiness / dissatisfaction (at least as judged by my end-of-day assessments).

I'm very sorry to hear about your dog. It's a very difficult thing to go through even without any predisposition towards depression.

This is probably an idiosyncratic thing that only helps me, but I find remembering that time is a dimension just like space helps a little bit. In the little slice of time I inhabit, a pet or person who has passed on is gone. From a higher-dimensional perspective, they haven't gone anywhere. If someone were to be capable of observing from a higher dimension, they could see the deceased just as I remember them in life. So in th... (read more)

That's the point of the article: agriculture allowed the Earth to support a vastly larger human population than it could have otherwise, but at a cost.

Personally I'm more optimistic than the author of the article I linked that the median quality of life of a human on Planet Earth will ultimately exceed the median quality of life of a human on an Earth where agriculture had never been developed -- in fact I think there's a good chance that that's already the case. But I don't think it's completely obvious, for reasons the author describes in detail.

Your claim was that it "remains to be seen" (whether agriculture turned out pretty well). I don't think it stands. Everything has a cost. I am aware of the Jared Diamond arguments, but note that they are based on comparison between ancient hunter-gatherers and ancient farmers. Contemporary agriculture is a wee bit different -- in particular, note the diversity of food it provides, as well as its ability to deliver food out of local season.

I guess whether > 3 mg/kg is a "lot" compared to other food types is relative to the number of food types the study considered.

I haven't dug up the France study to see how many foods they looked at that didn't make the >3 mg/kg cut, but the first study that I clicked on after searching Google scholar just now is a German study that found a median mg/kg of 160 for "cocoa powder" and 39 for "chocolate". Of the 1,431 food samples they tested, "77.8% had an aluminium concentration of less than 10 mg kg-1. Of the sample... (read more)

It's also relative to the amounts of these food types people normally consume. When chocolate has about the same amount as bread and vegetables, I don't see any reason to worry about chocolate.

I think it turned out pretty well.

Well, that remains to be seen.

No, I don't think it remains to be seen. How large a human population can Earth support without agriculture, do you think?
