Story that needs to get more attention: it appears that the major of Berlin has been deceived by a #deepfake video call. She thought she was talking to Kyiv major Vitali Klitschko. tagesspiegel.de/berlin/berlins…
A similar story that happened last year - deep fakes used to deceive European MPs.
Story in English by @dwnews. These are exactly the scenarios people working on #AI-enabled disinformation have been warning about.

November 2020: while still at #NATO, I was working on policy White Papers on #AI and on #autonomous technologies. Those were disseminated to Allied govts for feedback. They were not published, but we released a snapshot of the overall thinking here:

In 2021, I came back to NATO for a while to draft the first version of a more developed #AI #strategy for the Alliance. That work was then negotiated by Allied govts and agreed in Oct 2021.
NATO released a public summary of the Strategy here:

Anyone who did not see this coming does not understand #tech…(which includes people who design #AI).

“Important nuances were lost in translation when a rule commonly used to measure disparate impacts on protected groups in hiring was codified for easy-to-use tools…AI fairness”
Every time I see “our #AI will solve bias! Give us your #DEI budget!” win an #innovation award, accelerator, #hackathon I feel exhausted…

institutions would rather purchase ineffective & worsening-the-problem #tech than hard work of holding ppl accountable or change culture
And this is how #DEI - how currently approached - is ineffective & wastes money because a small amount of money is thrown at it with zero/minimal real hard work & unwillingness to be uncomfortable. Hence these bills: amp.cnn.com/cnn/2022/01/19…

"Kids are not simply little adults."

This adage is repeated countless times throughout med school re: physiology/pharma.

I think it should apply equally to #AI. That's why this headline from @AuntMinnie concerns me greatly.

In the referenced article, the authors set out to validate @Lunit_AI CXR tool on a cohort of pediatric CXRs.

The authors explicitly state in the abstract that the tool was developed for ADULTS, not kids.

Here are a few of the reasons why I'm deeply concerned by this:

#1 - We already have learned that #AI tools can fail unpredictably & inexplicably on data that falls within the distribution of the training data.

@fchollet It continues to be amazing that #neurons operate with action potentials which have a *maximum* frequency of a few hundred bits/second. One organizing principle is simply massive parallelism of very slow wetware units.
@fchollet Another principle is the analog processing capability of neuronal and dendritic membranes, e.g. dendritic action potentials.
@fchollet @fchollet Yet another principle from comparative anatomy and physiology is that brains reflect the structure of the body they inhabit and the motor/sensory needs of that animal. #AI has no physical body and no connection with natural selection to organize it.

The most impressive science in biotech right now is:

1. #iPSC
2. #AI/#ML in biotech
3. #SynBio
4. #CRISPR
5. #TPD
#iPSC has to be doing some of the most amazing science in the entire sector right now. The funny part is they don't get all the hype as the other hot science spaces. They are completely engineering cells that have many new functions and remove many old functions.
They are making all kinds of cells from stem cells into eye, heart, liver, pancreas and immune cells. They don't get much love because of the bad data of the allogeneic CAR-T programs, but some of these companies are completely disruptive.

1/ My new home @future just turned 1 🎉! Some thoughts on why I’m so excited about Future, by way of sharing a few of my favorite articles we’ve published so far. 🧵
2/ My colleagues share my optimistic outlook but get that building a better future won’t be easy. Many of my favorites tap into a common theme: science is integral to creating a better world, only if we (scientists) embrace new technologies and explore radical ideas, e.g.
3/ Science is slow, but it doesn’t have to be. One of the things slowing science down is the archaic process of funding science. Begging for #grants takes huge chunks of researcher time, decisions take months, and decision-makers are often risk-averse.

Happy to finally share our paper about differentiable Top-K Learning by Sorting that didn’t make it to #CVPR2022, but was accepted for #ICML2022! We show that you can improve classification by actually considering top-1 + runner-ups… 1/6🧵

#ComputerVision #AI #MachineLearning
Paper: arxiv.org/abs/2206.07290

Great work by @FHKPetersen in collaboration with Christian Borgelt, @OliverDeussen . 2/6🧵

@MITIBMLab @goetheuni @UniKonstanz
Idea: Top-k class accuracy is used in many ML tasks, but training is usually limited to top-1 accuracy (or another k). We propose a differentiable top-k classification loss that allows training by considering any combination of top-k predictions, e.g. top-2 top-5, 3/6🧵

In 2016, Science published the structure of the #NuclearPoreComplex—the sole gateway for macromolecules to enter or exit the nucleus.

A new special issue builds on that work, presenting the structure in unprecedented detail. fcld.ly/jfvwxfe (THREAD) 🧵 ImageImage
A composite structure of the cytoplasmic face of the human #NuclearPoreComplex provides a rich foundation for elucidating the molecular basis of #mRNA export and nucleoporin diseases, according to a new Science study. fcld.ly/3v012d9 Image
In a new Science study, researchers present a near-atomic composite structure of the human #NuclearPoreComplex’s ~64-megadalton symmetric core. The findings provide a basis for future functional studies. fcld.ly/wgoa4cj Image

(1) It's critical that advances in AI be understood by those from the humanities and creative arts. This is because commercially available AI will soon cross the point where, to paraphrase Arthur C. Clarke, it will become 'indistinguishable from magic'. #scifi #dalle2 #futurism Image
(2) When talking of magic “There are only two worlds-your world, which is the real world, and other worlds, the fantasy. Worlds like this are worlds of the human imagination: their reality, or lack of reality is not important. What is important is that they are there..." #dalle2 Image
(3) "...These worlds provide an alternative. Provide an escape. Provide a threat. Provide a dream, and power; provide refuge, and pain. They give your world meaning. They do not exist; and thus they are all that matters." (Gaiman) #dalle2 #NeilGaiman @neilhimself #London #Magic Image

We're well into the 3rd "large-scale" era of machine learning arxiv.org/abs/2202.05924 which has given rise to Foundation Models economist.com/interactive/br… and a recent controversy about whether LaMDA, a language model, is sentient #AI

I don't think people have fully grasped the power of full stack AI (e.g. combining transcription, editing, and visual generation) when it comes to helping engage with and grow or augment 'accepted norms' around culture and history. #AI #dalle2 #culture #history #art #gpt3
Personal histories are something that have historically been the preserve of privileged communities; with people from immigrant backgrounds, or those that have a rich history of oral storytelling, often having a much 'thinner' sense of their own sense of place. #dalle2 #immigrant
There are over 300m first generation immigrants globally; when you factor in second and third generation immigrants, along with migrants from nomadic or other similar communities the impact of this is well over a billion individuals. #dalle2 #AI #art #immigrant #nomad #history

What an incredibly odd and weak episode of “Streitkräfte und Strategien” on autonomous weapons. Germany has internationally renowned experts on this topic - @drfranksauer @adahlma to just name two - and @cschmiester presents this topic as if no one had ever heard of it.
I know not everyone follows this topic closely but over the last years it has been discussed in quite some detail in the German media. So going “oh wow, this Stuart Russell in this FT article warns of these systems” is just… weak sauce.
Just a few examples of recent media reports on this:

If anyone didn't get what I meant when I said @ykilcher chose to "kick the hornets nest" or if anyone was wondering about the cost of speaking out against unethical behaviour in #AI, here's a little summary of my recent twitter feed.

CW: transphobia

ImageImageImageImage
Here's some more. If anyone doesn't understand why all these statements are explicitly transphobic ... well, it is because you don't face it. These are all extremely hurtful.

That's enough, but I've skipped all the misogyny, racism, anti-semitism etc. ImageImageImageImage
This isn't isolated. Another commentator on this stunt has needed to take some time off Twitter due to the reaction.

I honestly spent several days deciding to post on this, because I knew what would happen. It was important, but there is always a cost.
