Not saying they are wrong, but my feeling is that selection effects probably dwarf any causal effects here. You don’t need much skew in the health distribution of people who are drawn to an intervention like this to get this kind of correla

Can you share more about the multi-vector approach? Is it open source?

It scales as log(N), right? So if you can tolerate it for a few hundred docs you can probably tolerate it for a lot more.

Can you really rent a cluster of 75 H100s for 75*2 USD per hour? Individual H100s, yes. But with sufficient interconnect to run these huge models?

24 hours? Wouldn’t it be better to do shorter bouts of scheduled unavailability so unknowing people’s systems will boot up without manual intervention, but still generate lots of nasty logs / alerts?

In 1998 when I was in high school I dreamt up this kind of power plant and asked my physics teacher where the power really came from. Not happy with his answer I asked a university physics Q&A service [1]. Not happy with their answer ei

I think it will be hard to expand psychiatry to that level while keeping it professional. The fundamental issue is that people ascribe personality flaws to others instinctually and also have strong feelings around being subjected to such tr

If you look into the history of psychiatry I think you’ll find quite a lot of examples when diagnosis and treatment was forced on people who didn’t want it. It’s not hard to find contemporary such examples either.

Thanks for the extensive answer. > I don't think the idea of a zero null hypothesis is necessarily mathematically unsound. In cases like the difference in means, a zero null hypothesis is well-posed. However, I agree with you that t

I asked Claude to dream it up instead. It was good.

Seems to be the press release for this article: https://www.nature.com/articles/s41928-025-01422-1 Anyone know where I can read it?

I’m not arguing that there’s something fundamentally wrong with mathematics or the scientific method. I’m arguing that the social norms around how we do science in practice have some serious flaws. Gwern points out one of them. One that IMH

Sure (and of course). But did you see the effect size histogram in the OP?

The problem is basically that you can always buy a significant result with money (large enough N always leads to ”significant” result). That’s a serious issue if you see research as pursuit of truth.

Also, even if you can prove the legitimate origin of the funds you can’t be sure that your bank will accept them. If you can’t find a bank that will accept them then formally you may still have the ”asset” but you can’t really use the money

Ok. I may have read a bit too much into this paragraph: > Order the items above, smallest fraction first, whilst taking into account the uncertainty in the number of trials to bound the probability of over-estimating each fraction. But w

The chain rule was explored by Gottfried Wilhelm Leibniz and Isaac Newton in the 17th century. Either of them would have ”invented” backpropagation in an instant. It’s obvious.

The answer looks a bit simplistic compared to the question (as I interpreted it at least). In order to estimate the risk of incorrect ordering you have to calculate P(p2 > p1) where p1 and p2 are drawn from different beta distributions.

Is there a better principaled approach to #1 than Monte Carlo sampling from beta distributions?

Interesting, thanks!

Why the hell do all those ”renowned institutions” need this (admittedly brilliant) guy to turn their crawl into a usable search engine? What’s wrong with this continent…?

You could train that architecture end-to-end though. You just have to run both models and backprop through both of them in training. Sort of like mixture of experts but with two very different experts.

If you are only capable of blind trust or distrust then there’s a huge difference between human experts and LLMs (and it’s of course wise to put your blind trust in a human, not an LLM). But if you have more of a ”trust no one” or ”trust bu

To be clear I have nothing against the prevailing psychotherapeutic industry. I’m very thankful for that part of the mental health community. I think it’s rather well-aligned with TikTok too, btw.

> You aren’t able to submit to main without first uploading a change or stack of changes to code reviews, then you submit the changes after they are approved. Well… On a conceptual level I’d call that a feature branch.

I fully agree that the night seems dark. But having recovered from a state that many institutionalized professionals deemed hopeless I have a different perspective. Have you seen One Flew Over the Cuckoo's Nest? I think it serves as a
