Equivariance meets RNNs. An exciting research direction!
Why do video models handle motion so poorly? It might be lack of motion equivariance. Very excited to introduce: Flow Equivariant RNNs (FERNNs), the first sequence models to respect symmetries over time. Paper: arxiv.org/abs/2507.14793 Blog: kempnerinstitute.harvard.edu/research/deepe… 1/🧵

Dear US congressman, have you considered that it may not be the same individuals holding the hostages and the ones dying from hunger? Many thanks 🙏
Release the hostages. Until then, starve away. (This is all a lie anyway. It amazes me that the media continues to regurgitate Muslim terror propaganda.)
Gazan sodan on loputtava nyt. 24 ulkoministerin yhteisessä lausunnossa vaadimme Israelia noudattamaan kansainvälistä humanitaarista oikeutta ja poistamaan humanitaarisen avun toimituksia koskevat rajoitukset. Vaadimme Hamasia vapauttamaan panttivangit viipymättä ja ilman…
Annie Ernaux s'exprime sur Gaza, parole dérisoire face a une machine de destruction que rien ne semble plus pouvoir arrêter, et qui met en cause l'existence même de nos "valeurs" en Europe et aux US.
Annie Ernaux, prix Nobel de littérature, prend la parole 🗯️ Son message est grave, nécessaire, et s’adresse à chacun d’entre nous.
My first PhD project just hit arXiv! We demonstrate how classic geometric descriptors (well-established mathematical tools like the Heat Kernel Signature) can power new, efficient methods in Topological Deep Learning. 1/2
Israel is starving to death 500,000 Palestinians in Gaza right now. “Families told me there are days their children are not eating at all … mothers are telling me how they're trying to have kids not play so that they don't draw more energy.”
Chaque jour à #Gaza, 10 enfants perdent une jambe ou deux. Chaque jour. C'est ça la réalité des massacres israéliens. Elle foudroie. Source :
And 10 children per day lose one or both of their legs. 20 months of intense hostilities have destroyed the protection environment for persons with disabilities and older persons. Protection Cluster outlines 5 key protection risks in this regard requiring immediate attention.
Excited to share new work @icmlconf by Loek van Rossem exploring the development of computational algorithms in recurrent neural networks. Hear it live tomorrow, Oral 1D, Tues 14 Jul West Exhibition Hall C: icml.cc/virtual/2025/p… Paper: openreview.net/forum?id=3go0l… (1/11)
🧵0/7 🚨 Spotlight @ICML2025 🚨 Chi-Ning and Hang have been thinking deeply about how feature learning reshapes neural manifolds, and what that tells us about generalization and inductive bias in brains and machines. They put together the thread below, which I’m sharing on…
Face aux crimes israéliens, l’UE choisit l’inaction et le déshonneur. Le conseil européen des affaires étrangères n’a finalement rien statué sur son accord d’association avec Israël, pourtant bafoué. L’Europe est ainsi complice des crimes de Nétanyahou. mediapart.fr/journal/intern…
- Pouvez vous garantir que données françaises confiées à Microsoft ne seront jamais transmises à des autorités étrangères, dans le contexte actuel, plutôt américaines, sans l'accord explicite des autorités françaises ? - Non, je ne peux pas le garantir.
It's not a very good system. There are some good community journals which are non-profit. In my field(s) of ML and neuroscience I know TMLR, JMLR, JoV, eLife, Imaging Neuroscience, others?
Super excited to share our new paper! We spent the past years building an alternative AI approach, and now we demonstrate a whole range of advantages. Robust object & pose detection, generalization, data and compute efficient training, continual learning, shape bias, and more!
2/ The first paper: “Thousand-Brains Systems: Sensorimotor Intelligence for Rapid, Robust Learning & Inference”, is out now: arxiv.org/abs/2507.04494. It showcases our first working system, codename Monty.
Many people think of the brain as a hierarchical system, and in many ways it is. But there is also a lot of non-hierarchical processing going on. Check out this pre-print where we review and propose functional roles for the different long-range connections in the neocortex 🧠
New paper dropped! “Hierarchy or Heterarchy? A Theory of Long-Range Connections for the Sensorimotor Brain” The Thousand Brains Theory explains the cortex’s non-hierarchical connections, and why they matter for building machine intelligence. Read it now: arxiv.org/abs/2507.05888
