Inspired by #Schrödinger I have maybe got a non-lethal solution to Australia's #feralcat problem.
If we put out a very large number of cardboard boxes...

Large language models are essentially solutions to nonlinear optimization problems to predict the next token in the output text. Mathematically, these problems are quite similar to problems we routinely face in physics, like finding the ground state of a quantum system.
In these physics problems, we observe a recurring pattern: First, someone comes up with a new class of solutions (we call this a "variational ansatz") and there is tremendous progress, allowing to solve previously hard problems in a near-miraculous way. However, once the low-hanging fruits have been reaped, the remaining problems stay hard. Throwing vastly more computing power at it helps a little bit, but produces quickly diminishing returns.
I'm pretty sure that's exactly what has happened with the advent of transformers for natural language processing.

It takes 10 hours on a laptop accurately simulating 5 seconds of a worm wiggling: https://archive.is/0j2Jp (and we still cannot simulate more than 20-30 #quantum particles exactly). Please be humble when the universe is present! #modeling #complexity (through @loriemerson )

I almost overlooked that I've been on #Mastodon for a full year now. I must say, I was sceptical in the beginning, but I feel that we have been making continuous progress in terms of reach and interesting content, while at the same time not falling for too excessive spam. Keep it up 👍!
Since many scientific institutions have joined in recent months, and with them hopefully many more scientists, it's maybe time for an updated #introduction
I'm a theoretical physicist who works as a postdoc at the Math Institute in Oxford 🐂. My research is about #quantum field theory, with an emphasis on combinatorics. Some aspects are rather "hands on", such as the numerical values and distribution of Feynman integrals, which is input for new numerical methods to compute scattering cross sections. Other aspects of my work are rather mathematical, such as the relationship between topological field theory and the cohomology of the odd graph complex. I have a website that contains a summary of my research and a sporadic blog about my postdoc life and what to do with physics in real life. https://paulbalduf.com

Please share: Our Max Planck Institute recently left X and is present here on Mastodon. Give them a follow! Beautiful pictures from the science of light!

#ClimateDiary even with low expectations, even having zoned out almost for its entire duration, i still can’t help being deeply saddened that #COP29 was such a huge disappointment for so many countries in the Global South bearing the brunt of #ClimateBreakdown - #ClimateFinance support, fhe #Quantum, was abysmally small. I listened to outraged Nigerian and Gambian reps and it was just 💔

The EU is investing €380M for a photonics pilot factory.
€133M euros are being allocated to production lines in Twente and Brabant in the Netherlands with co-funding of €66M from the national Dutch budget. The Nederlands have the ambition to produce by 2030 100000 wafers annually. Via @marchijnkNRC
