This is incredible
Physics-AI that can generalize across different complex 3D geometries is a challenging problem. We propose a principled solution combining Neural Operators with Optimal Transport. Optimal transport provides determines the most efficient transformation between two densities. By…
It is interesting that the new @deepseek_ai v3.1 is trained using the UE8M0 FP8 scale data format which is logarithmic number system. Our multiplicative weights update (Madam) for training in that format was done several years ago while at @nvidia It yields maximum hardware…
My longtime collaborator Dave Patterson (long-time faculty at @UCBerkeley, @TheOfficialACM Turing Award winner, and fellow @LaudeInstitute board member) wrote a very good op-ed about how continued investing in basic science and technology research is essential for the U.S. Dave…
New Anthropic research: Persona vectors. Language models sometimes go haywire and slip into weird and unsettling personas. Why? In a new paper, we find “persona vectors"—neural activity patterns controlling traits like evil, sycophancy, or hallucination.

New Anthropic Research: “Inverse Scaling in Test-Time Compute” We found cases where longer reasoning leads to lower accuracy. Our findings suggest that naïve scaling of test-time compute may inadvertently reinforce problematic reasoning patterns. 🧵

A surprising & little-known results in classical statistics: Mean (μ) and median (m) are within one std deviation: |μ−m| ≤ σ For unimodal densities, bound is even tighter |μ−m| ≤ 0.7746 σ This beautiful results first appeared in a 1932 paper by Hotelling & Solomons 1/3

These pictures will be amazing! The Legacy Survey of Space and Time is an incredible feat of science and engineering that will image the entire southern sky every 3 nights for 10 years generating 20TB of data per night, yielding a new window into our universe and how it changes.

New paper on the generalization of Flow Matching arxiv.org/abs/2506.03719 🤯 Why does flow matching generalize? Did you know that the flow matching target you're trying to learn **can only generate training points**? with @Qu3ntinB, Anne Gagneux & Rémi Emonet 👇👇👇
A new Science study finds that different dendritic segments of a single neuron follow distinct rules. The results challenge the idea that neurons follow a single learning strategy and offer a new perspective on how the brain learns and adapts behavior 📄:…
Since 1945, American Universities have been envied worldwide for their Government-funded research. Hard to justify via corporate R&D, frontier science is vital to our long-term health, wealth, & security. To withhold such funding is to amputate the engines that Make America Great
