“That day, we realized the Russians had come to kill us” is how one theater survivor put it to me. “They didn’t come to fight with Ukrainian soldiers. They just wanted to kill us.” from James Verini, an excerpt from his book "The Theater" www.theatlantic.com/internationa...

[1/5] 🇲🇦 Today I’m presenting our paper “Orthogonal Representation Learning for Estimating Causal Quantities” at AISTATS 2026 in Tangier, Morocco; and I’m very happy that it was accepted as an oral.

[1/5] 🇧🇷 Looking forward to presenting our new paper, “Overlap-Adaptive Regularization for Conditional Average Treatment Effect Estimation,” at ICLR 2026 in Rio de Janeiro. The paper tackles a core challenge in causal ML: estimating treatment effects when overlap is low.

[1/4] 🇧🇷 Excited to share our new paper, “GDR-learners: Orthogonal Learning of Generative Models for Potential Outcomes,” which I’ll be presenting at ICLR 2026. The goal: better estimate potential outcome distributions from observational data — not just averages, but the full uncertainty.

”The consequence of a newly unreliable and even hostile United States, therefore, will likely be significant military buildups by former allies. This will not mean sharing the burden of collective security, because these rearmed nations will no longer be American allies.”

If Europe ends up buying Russian oil refined in India, through the new India-E.U trade deal, I will have an aneurism.

Ukrainians enjoy winter despite Russian attacks.

So there’s a website called Deer Of St Nicholas which posts Christmas wish letters from Ukrainian children who had their childhood stolen by the war, anyone can pick a child and get them their present and it’s that time of the year again to achingly scroll it for hours again

Timeline is just death, death, bodies, explosions, rubble, death, when will this day be over

“The United States remains committed to supporting the Russian people as they continue to build on their aspirations for a brighter future”

🧵 1/3 Dear friends, I ask everyone again for help! You know the situation in Ukraine is tough at the moment: After the deadly attack on Sumy in Ukraine last Sunday I felt speechless. Yet there is a way to help and even a small contribution might eventually save someone’s life.

A grim reminder of the real nature of the “Christian Europe” that Putin and his far-right stooges have in store for us all.

Countless emails asking how Americans can directly aid Ukrainian soldiers. Here’s an easy answer: savelife.in.ua/en/

Catherine from Zaporizhzhia. She spent 5 hours under the rubble of her house, destroyed by a Russian missile. All this time she has been hugging her cat. P.S. Sorry she didn't wear a suit.

Over the last month we’ve seen the death of the post-WW2 era of American allegiance with Europe and most Americans don’t even know it happened

Guys, I get that the instinct is to save face, but don’t downplay this as mere rhetoric. This is the U.S. abandoning all its international integrity and dismantling the post-war, rules-based order. You need to do something about it now!

Once again I am leaving the Munich Security Conference in a low mood. Amongst all the noise, the US signalled their plans for Europe, so things are becoming clearer. But things are clearly not good. This is what we now know, and what we have to do about it:🧵1/17

1/n Excited to present our new work, done at the van der Schaar Lab at the Cambridge University together with Mihaela van der Schaar and Stefan Feuerriegel. 📍7008 western ballroom, 11:00-14:00 #NeurIPS2024
