Graduate students enter cognitive science from diverse disciplines, bringing different levels of mathematical training. 🧶

I’m very happy to share a new #Maths_Training website for cognitive science students that we developed this semester, designed to help bridge different mathematical starting points and covering probability, statistics, linear algebra, calculus, differential equations, and more.

The material is organized into two tracks: 1) Basic Track that builds the foundations progressively, especially for students from humanities and social sciences, and 2) Advanced Track for students who already have more mathematical training. Each session includes 📊 slides, ✏️ exercises, and ✅ solutions.

This semester, I’m teaching the Maths Training Crash Course at the Département d'Études Cognitives, Ecole normale supérieure, together with Sara Moussaoui and Prof. Amaury Lambert as the supervisor. We designed the website as a practical resource for learning, reviewing, or simply coming back to the mathematical concepts that appear again and again across cognitive science.

We initially built it for our CogMaster students, but we hope it will be useful to students and researchers elsewhere too. Feel free to explore it, share it, and send us feedback!

Tom McCoy @rtommccoy.bsky.social · 01/09/2026
🤖🧠NEW PAPER🧠🤖 (The result of an 8-year project!) LLMs seem very different from symbolic systems. Yet LLMs excel in symbolic domains (e.g., language/code/math). How do they do it? Our finding: LLM representations have implicit symbolic structure! Link in thread ⬇️ 1/n
Overview of the paper. 
Title: The Emergent Symbolic Structure of Artificial Neural Networks
Authors: Tom McCoy, Paul Soulos, Tal Linzen, Paul Smolensky
Left: Neural networks encode information in vectors (there is then an image of a vector), yet they excel at tasks long thought to require symbolic structure (there is then an image of a symbolic representation, specifically a syntax tree). How do LLMs do it?
Right: We find that LLM representations can be closely approximated with symbolic structures. This approximation lets us edit the structure of an LLM’s output by editing the structure of its internal representations, as shown. There is then an image of two edits to LLMs. In the first one, the original input is 3 + 6 * 8, with an answer of 51. But if we swap the positions of the 3 and the 6, the output becomes 30. In the second one, the original input is a Python command repeating the list [Z, U] three times, producing [Z, U, Z, U, Z, U]. But if we edit the input in a way that adds a Q at the end of the input, the output becomes [Z, U, Q, Z, U, Q, Z, U, Q].
