It's so much nicer to referee papers which have public #opensource software with #replicability, #reproducibility, #reusability #RRR!
I have now started to transition to the other app. I will not post science here. Interested in the science of me and my coworkers? Same username. This platform has been used for manipulation of public opinion by the owner. Fingers crossed 🤞 interesting folks will transition too

I encourage everyone here to look for other platforms. Several of the people I appreciate have already moved.
1/ X's algorithm was changed in mid-July 2024 to systematically boost Republican-leaning accounts and Elon Musk's own account following his endorsement of Donald Trump, according to a newly released computational study of engagement from the Queensland University of Technology.⬇️

It's always a pleasure to improve the learning experience for students. This edition of the matrix computations course involved a lot of new videos. Learn about matrix sign computation in 5 minutes. 🤓

On my way to the office early morning. Or is it Hogwarts? I hope the exams have been magically corrected by themselves. #KTHuniversity

I have two books in Russian in my office. Published in Kiev, Ukraine, Soviet union. The Ukrainian people have the right to decide their future. Including language. 🇺🇦

A lot of attention how chatgpt will disrupt teaching. On the contrary, teaching has a lot to gain from this technique.

Beware of using #chatGPT for math. Here is its answer to the exam question in my course in numerical linear algebra. Looks very convincing but most of it is completely wrong. And also self-contradictory.

Applications for the Master's programme Computer Simulation for Science and Engineering (COSSE) is open. Teachers from KTH, TU Berlin and TU Delft. Modeling, numerical analysis, computer science, high-performance computing, etc. Highly research-oriented.

What has been erased in the formula for Krylov approximation of the matrix function? Ping @guettel. The students wanted space to write DAEs when we recorded it 😂.

Machine Learning and #linearalgebra has so much to gain from each other. Terminology is the first bottleneck. Unit vectors and one-hot vectors are the same thing. 🙈

New theoretical ways to improve matrix matrix multiplication found. Cool. 😎 Would have been even cooler if they actually solved the problems with Strassen: communication and stability. nature.com/articles/s41586-0… – at Stockholm, Sweden

The new 3d-force-graph data exploration framework by @vastur et al is just awesome. Ever wanted to travel in the deep space consisting of MNIST 3's and 8's? #datascience
