Scaling laws don’t just show up in test error — they leave fingerprints in the weight spectrum.
In the feature learning regime, we map this connection: phase diagrams of scaling exponents <-> spectral signatures of trained weights. The paper is: arxiv.org/abs/2509.24882

While I contributed to this line of work and to this piece; I’m quite sure that modern AI would exist even without Hopfield and Hinton. There is a huge community behind each influential concept, and while prizes are given to individuals, it is the community that creates the science.
The 2024 Nobel Prize in Physics went to Geoffrey Hinton (left) and John Hopfield for their work on the statistical physics of neural networks. Modern AI would not exist without their clever methods of studying and applying randomness. www.quantamagazine.org/the-strange-...

I am doing just that since about a decade! No Elsevier no Nature/Springer I do not review for them, do not publish there. I refused a couple of editorial boards with them, numerous special issue invitations. If a young colleague writes in their cv this is their moral code I would deeply respect it.
What would happen if tomorrow we all stopped publishing in journals published by private, for-profit publishers? #MathSky
