I fully agree with @emilymbender.bsky.social here 👇 E.g. what Mistral's CEO recently proposed to the EU parliament, trickle down responsibility won't work. We need accountability from all model makers!

But we also find there is great variability across countries, suggesting complex interactions between country morphology and dataset overlap. We determine this by building individual ML models for each country. These models show coefficients importances can greatly differ between countries

To understand this in detail we built global machine learning models to predict (for 82 million 100x100 meter cells) where datasets agree. We found that geographic and socio-economic factors considerably impact overlap.

We evaluate dataset overlap at 100 x 100 meter cell resolution, and find that datasets, on average, agree, only on for 42.6% of all cells 🧐 However, we also find great variability across countries. For some countries the overlap is high (close to 1), for others its horrible (close to 0)

In our paper we look at 3 popular settlement maps for 44 African countries:
- Open buildings (by Google)
- High Res Pop Density Maps (Meta)
- Global Building Footprints (Microsoft)
We study where they agree, where they disagree, and more importantly, try to figure out why they disagree

This is crazy ....especially considering the DSA only applies to EU citizens and any data collected from them in the EU 🤷

The: "not to apply the DSA if it jeopardizes the freedom of Americans", is just silly as the law does not affect the US. Only US companies operating in the EU and their EU users

Hej @politiken.dk, nu er jeg ikke journalist, og er måske ikke så inde i den finere journalistiske nuancer, men jeg synes der mangler noget information i overskriften her.

Hvem har dræbt de 73 personer?

Gad vide hvad Mette Frederiksen siger til dette? @socialdemokratiet.dk

Når en tidligere israelsk premierminister tilslutter sig koret, mener den danske statsminister så stadig at sanktioner og boycott ikke er nødvendige?

USSR in 1990 vs what the US seemingly is moving towards in 2025-26

104% tariffs 👀

I don't understand this trade war. It seems like the americans are fighting their own capitalist system.

On the one hand they are pushing for laissez-faire economic policies, while at the same time they are angry that people are free to import from any country 🤷

Holy hell 👀....

75% of surveyed researchers say they are considering leaving the US

If countries want to poach top research talent, now is the time

Anyways, selv hvis Grønland manglede et selv-styre godtgører dette faktum ikke en ekspropriation/konfiskering af national ressourcer

Jeg abonnerer ikke på JP og kan ikke læse artiklen. Men artikler der henviser til den skriver at afgifter fra minen dækkede Grønlands udgifter i 8 år og ca. drejede sig om ~2% af den totale indkomst af minen.

Det ændrer staig ikke på at minen stadig gav en fortjeneste som ikke kom Grønland til gode
