In a new essay from our "Artificial Intelligence and Democratic Freedoms" series, @randomwalker.bsky.social & @sayash.bsky.social make the case for thinking of #AI as normal technology, instead of superintelligence. Read here: knightcolumbia.org/content/ai-a...

They are graded on giving full proofs. LLMs are quite bad at that. Though I’m sure there’s also quite a bit of test data leaks going around

Tangentially related: interesting to think of the biblical law of jubilee in this context. It says that every 50 years debts are dropped, indentured servants released and land is returned to “original” owners

This piece from August seems like a good writeup: mathscholar.org/2024/08/new-... It mentions a new book from 2024 by Jack Szostak and Mario Livio called “Is Earth Exceptional? The Quest for Cosmic Life”. Szostak is a leading scientist in the field (I haven’t read the book yet)

to be fair, ICLR is a far cry from what Yann is suggesting in that piece. I'm not questioning the need for reform. My question is why didn't the push for reform succeed back then, and what can we learn from that? (in the spirit of "Everyone will not just")

I recall that Yann LeCun had some interesting suggestions back in 2013-2014. Despite his clout the community didn't move much* yann.lecun.com/ex/pamphlets... *ICLR public reviews and TMLR are small steps which I think followed from the discussions going around back then

This is such a good point, and I love the connection you're making in the paper to resilience to hidden confounding. In many cases the treatments that would shift are exactly those that have more "exogenous randomness" in them, and for these units the effect might be more easily identified from data

Instead some scientists just said “close schools!” , conflating their own priorities with science and hurting the credibility of scientists overall. Their intentions were good but I think the overall outcome is not 2/2
220
Uri Shalit @urish.bsky.social · 22/11/2024
an example where I think some scientists stumbled: during COVID after the first few months, imo a responsible scientist would say “closing schools has these benefits and these harms (w/uncertainty), the politicians and public should weigh them and decide” 1/2

Related to this, been enjoying this paper by Icard, @jfkominsky.bsky.social & Knobe looking at how "normality" affects the way humans judge causes. eg in when you need two factors to cause an event (say oxygen + match to cause a fire), humans will judge the less "normal" element to be more causal

Normality and actual causal strength
Existing research suggests that people’s judgments of actual causation can be influenced by the degree to which they regard certain events as normal. …

I don’t know about other domains, but in healthcare I’ve seen the term used to basically mean “a model of how a patient would respond to a treatment other than the one they’ve actually received”. When used in that sense it’s just corpo ai brainwash as @natolambert.bsky.social said

Uri Shalit @urish.bsky.social · 17/11/2024
While I think this is a great paper, I also think that the focus on causal features (which is only part of what the paper is about) is a bit of red herring bsky.app/profile/uris...

OTOH consider a severe headache. While the pain itself is probably not immediately causal, it’s a strong and stable symptom of underlying conditions and this it’s a stable feature. Indeed almost any classic diagnosis of disease by symptoms is anti-causal yet stable (3/3)

Uri Shalit @urish.bsky.social · 17/11/2024
E.g. consider the time of day someone goes into an ER. That might influence who sees them and how quickly which will influence many downstream outcomes causally. But the specifics of this effect will vary wildly between different ERs making this an unstable feature (2/3)
130
Uri Shalit @urish.bsky.social · 17/11/2024
To be fair, I think there’s no strong reason to think that causal features are a priori more stable than others (1/3)

The milk in Hersheys chocolate goes through lipolysis, which breaks down some of its fatty acids in order to extend shelf life. The problem is that lipolysis yields butyric acid, an acid which is literally found in vomit and gives Hersheys that very specific revolting taste

I think this is only a threat if: 1. Revs. who would have written quality reviews now write bad reviews because they can use ChatGPT, and/or 2. ACs who would previously recognize bad reviews would miss some because they're masekd in ChatGPTese I might be wrong by IMO none of these is a big threat?
