Would you like to come to my lab for a postdoctoral position? Apply for the EPFL AI Centre fellowship: epfl.ch/research/fun.... FYI, I have funding (ERC & Simon's collaboration) also for 1-2 top candidates who will not secure the fellowship. Same for
@krzakalaf.bsky.social lab.

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-...

Excited about our progress in characterizing The Computational Advantage of Depth in Learning with Neural Networks. Check out the number of samples that can be saved when GD runs on a multi-layer rather than on a two-layer neural network. arxiv.org/pdf/2502.13961

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 No Elsevier no Nature/Springer I do not review for them, do not publish there.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

Our advance in statistical physics analysis of simple graph convolutional neural networks arxiv.org/pdf/2402.03818 will appear at the Learning on Graphs conference: logconference.org. My student Odilon has now extended this to the multi-layer case, so more is coming soon.
