And one of the interesting (and hard) computer science problems is how to turn an arbitrary einsum expression into the most efficient series of operations (transpose, matmul, etc.) available in hardware kernels. This is mentioned in the post under "How Contractions Are Actually Computed".

Really sad - he was often the sensible voice in the UK media (e.g. BBC articles) when it came to security issues.

There was actually a lot of pushback against the austere aesthetic by government ministers - they wanted fancy looking photo banners and pretty things. This was pushed back on in the name of making something functional the prioritizes users.

Honestly this sort of climate & environment tokenism frustrates me - spending a lot of energy trying to reduce and elimate things that barely matter (or even actually make things worse by displacement), while ignoring the big ticket items. At best it's innumerate, at worst it's greenwashing.

Harry Nyquist isn't exactly an unknown engineer who doesn't have his own achievements, though - not sure why people are saying he would be fired in a modern company!
tfgg | 2 years ago | on: Social media decline: Users are shifting to messaging apps and group chats
What was remarkable is how Facebook's Threads app jumped straight to being full of advertisers and hucksters - they didn't think that maybe the right way to bootstrap a social network would be to make it full of authentic conversations, at least to start with.

We're bad at onshore wind, not due to lack of possible sites, but because of a government ban on building it: https://www.theguardian.com/environment/2022/nov/29/onshore-...

Why? At what level do you define "local" - country, state, city, neighbourhood, street, literally next door, just my house?

Social media owners wanted all the benefits of superscale communities with none of the responsibilities - it isn't surprising that moderation got worse.
Reddit vaguely has a workable approach with subreddits, but it's still high variance, and they have to discourage long-lived comment threads.

I'm not going to detail challenges in medical ML - the literature can do that. But just to mention one that other people haven't that goes beyond just precision-recall: algorithms can be biased based on variance in physiology (e.g. more accurate for men), and understanding how an algorithm is biased is very important for the person interpeting the information, who should be a trained doctor.
And it doesn't matter what his credentials are, that's appeal to authority. If he thinks this should be used and trusted by people for decision making, then he should submit it to independent peer review and regulatory approval.

So you should ignore it and see a doctor regardless.

Thermometers are well understood, simple devices, and there are other complementary checks (e.g. does my forehead feel hot) if they fail.
This project might lead to people thinking they're in the clear and not seek appropriate medical treatment, or be overtreated due to an error. You should always talk to a qualified doctor if you're concerned about your health, and not use projects like these for decision making.

What peer review or regulatory approval process has this been through? Seems pretty irresponsible -- there are many notorious pitfalls encountered with ML for medical imaging. You shouldn't play with people's lives.

The best thing to do these days is use an AlphaFold prediction, if there exists a confident one, as a starting position for refinement.

There's a responsibility under refugee conventions to take on people needing asylum. The conflation of them with illegal immigration is quite ridiculous. The UK is a rich country (~6th highest in the world), we should shoulder some of the (small) burden that we're asked to - many other, poorer, countries take on much higher refugee burdens.

I'm guessing here that ASA is 'American Statistical Association', rather than say, the UK's 'Advertising Standards Authority'?
tfgg | 7 years ago | on: Tokyo medical school admits changing results to exclude women
Funny how when confronted with an article that gives a clear, unambiguous demonstration of how patriarchy negatively affects women, you come up with two weak articles that supposedly demonstrate cases where women were advantaged (they weren't). From that, I'm led to believe that maybe the opposite actually isn't more common than I think.
Maybe you don't actually think that the issue in the Tokyo medical school was such a big deal after all?
tfgg | 8 years ago | on: Computing Fractional Fourier Transforms
Could you elaborate why you think it looks like a fractional FT?
If you solve Schrödinger's equation with periodic boundary conditions on the potential what you get are Bloch functions, which are the product of a phasor and a periodic function.

I hope positively surprised :) That's Paul Carter - he's a regular presenter on the BBC, particularly their tech show "BBC Click". Here's a nice interview (https://disabilityhorizons.com/2019/09/paul-carter-journalis...) he gave to Disability Horizons a few years ago about his experiences.
