Both studies highlight experience-driven emergence of number coding. Excited to see computational evidence that learning to count, not just architecture, makes networks focus more on number. openreview.net/forum?id=AJm...

Our CCN2025 results (Investigation of Numerosity Representation in Convolutional Neural Networks – CORnet-Z) find intrinsic numerosity amplified and shifted earlier in the hierarchy.

Nice work by Lauren Aulet showing that counting training flips an architectural area bias into a strong number bias in ResNeXt-50.

Are you a neuroscientist with great coding skills, or a software engineer interested in the brain?

We are recruiting for a research software engineer to help us build pipelines to process weeks of neural and behavioural recordings from freely moving animals.

The "publish or perish" culture must perish. Scientists need time to think.

We just published our Slow Science Manifesto, where we argue that huge changes are needed in the way we fund, publish, and evaluate science.

Excited to launch Principia, a nonprofit research organisation at the intersection of deep learning theory and AI safety.

Our goal is to develop theory for modern machine learning systems that can help us understand complex network behaviors, including those critical for AI safety and alignment.

Thrilled to finally share this work! 🧠🔊

Using a new reinforcement-free task we show mice (like humans) extract abstract structure from sound (unsupervised) & dCA1 is causally required by building factorised, orthogonal subspaces of abstract rules.

For the past 3 years, I've taught a course on Machine Learning for Climate Change to undergrads. At times, people have asked if the course lectures could be made available online. While I can't offer that, I have decided to start making "5 Minute Papers on AI for the Planet" videos. Hope its useful!
