Iranians are experiencing a collective trauma. Thousands have been killed/injured in recent events, the economy is crippled & the threat of a wider conflict is real. This is especially difficult for those living in Iran, as many have lost (or fear losing) loved ones. www.nature.com/articles/d41...
Hats off to the great Anne "I don't do fancy" Treisman!

๐ค If you're interested in our latest results, comparison with existing approaches or just curious about new theories for learning in the brain, stop by!
๐ The key result: Our learning rule is a form of contrastive Hebbian learning and recovers the exact gradients through time!
Amazingly there is a new alternative to BPTT in town: RHEL==Recurrent Hamiltonian Echo Learning (Pourcel & Ernoult, 2025)! We took inspiration from Hopfield energy models to design a novel Hamiltonian NN. In our model, neurons are now second-order oscillating ODEs that can be trained using RHEL...
๐ข Presenting our work at #NeurIPS2025 ๐บ๐ธ today (6-9 pm) @wimlworkshop.bsky.social!
๐ง The question: How can the brain learn temporal dependencies without an artificial backward pass? BPTT is notoriously harder than BP and is still uncharted territory (Lillicrap & @adamsantoro.bsky.social , 2019).

Et je viens de voir passer de strip de @unpied.bsky.social qui rรฉsume pas mal ce qu'on peut penser de cette histoire.
With @eliamascolo.bsky.social we developed an interactive class on biological evolution (focusing on mutations ๐พ) for science #teacher through a card game ๐ฒ We crash-tested it with #HighSchool students from Milan and made it available online for broader use: replicards.netlify.app #SciCom #EvoBio
