- Not despondent to share our new work arxiv.org/abs/2601.17427 with Santiago Acevedo and Cristopher Erazo from SISSA, where we show that Binary Intrisic Dimension (BID) [ nature.com/articles/s42... ] is able to detect phase transitions in the Hopfield model. 1/N

View full threadWe look forward to applying this approach to study intrinsic dimension in non-equilibrium systems and neural representations in quantized neural networks. 4/N
- Finally, a call to the neuroscience community: the BID is the perfect tool to study low-dimensional dynamics directly at the level of spikes in both spiking network models and data. Feel free to get in touch if you're interested in collaborating. N/N
- We directly link the BID estimator for the intrinsic dimensionality of the spin dynamics to the overlap distribution in finite-size systems. 2/N
- We find that the BID scales sublinearly in the spin-glass phase, with changes of scaling exponents sitting at phase transitions. 3/N
- Please RT - Open PhD position in my group at the Donders Center for Neuroscience, Radboud University. We're looking for a PhD candidate interested in developing theories of learning in neural networks. Applications are open until October 20th. For more info: www.ru.nl/en/working-a...
- Just got back from a great summer school at Sapienza University sites.google.com/view/math-hi... where I gave a short course on Dynamics and Learning in RNNs. I compiled a (very biased) list of recommended readings on the subject, for anyone interested: aleingrosso.github.io/_pages/2025_...
- Very surprised (but very excited) to announce that I’ll be officially starting as an Assistant Professor at Johns Hopkins in the Electrical and Computer Engineering Department and as part of the new Data Science and AI Institute in July 2026!
- Fantastic. Congrats Will.
- Our paper on the statistical mechanics of transfer learning is now published in PRL. Franz-Parisi meets Kernel Renormalization in this nice collaboration with friends in Bologna (F. Gerace) and Parma (P. Rodondo, R. Pacelli). journals.aps.org/prl/abstract...
- Announcing our StatPhys29 Satellite Workshop "Molecular biophysics at the transition state: from statistical mechanics to AI" to be held in Trento, Italy, from July 7th to 11th, 2025: indico.ectstar.eu/event/252/. Co-organized with Raffaello Potestio and his lab in Trento.
- Our paper on density of states in NNs is now published in TMLR. We show how the loss landscape in simple learning problems can be characterized by Wang-Landau sampling. A nice collaboration with the Potestio Lab in Trento, at the interface between ML and soft-matter. openreview.net/forum?id=BLD...
- Excess kurtosis strikes back.
If you missed it at the #NeurIPS2024 posters! Work led by @leonlufkin.bsky.social on analytical dynamics of localization in simple neural nets, as seen in real+artificial nets and distilled by @aingrosso.bsky.social @sebgoldt.bsky.social. Leon is a fantastic collaborator + looking for PhD positions!
