Excellent resources put together by my peers at @mila-quebec.bsky.social and collaborators. I've been working on Continual RL since the start of my PhD, and I wish I'd had a resource like this. Whether you're new or looking for a deep dive, this is an excellent place to start.

Who's going to ICML in Seoul? I'll be there presenting our work and would love to meet people working on NeuroAI, RL, computational neuroscience, and biology. Feel free to send me a message. And if you're organizing any social events, I'd love to hear about them!

Excited to share our new paper accepted at ICML 2026 with @tyrellturing.bsky.social and Doina Precup! 🇰🇷 See you in Seoul. A major challenge in continual reinforcement learning is balancing: • plasticity (learning new things) • stability (not forgetting old ones) 🧵 1/15

After a fantastic week of discussions at COSYNE, I’m excited to now be in Amsterdam for the Winter School on Foundation Models. I am interesting in developing foundation models that can continuously learn, adapt, and reason. If you’re around, I would love to connect! 🇳🇱

Thrilled to see this paper finally published! The manifold representations in Figure 1H were a key inspiration behind the visualization of Successor Features (SF) in our recent SF paper. It's fascinating how insights from neuroscience can help us interpret representations learned in deep RL.

Lately, foundation models like BrainGPT & Cognitive FMs are dominating AI & science. But is our future solely built on these models? What about alternative techniques? How do we keep our scientific ecosystem diverse? As a community, where do we see the future of NeuroAI?

I've been arguing that we will be able to train foundation models on neural data from different species, because I suspect that there are sufficiently preserved motifs in neural computation across the phylgenetic tree. This paper appears to support that idea! www.cell.com/cell/abstrac... 🧠📈 🧪
cell.com
Multiscale organization of neuronal activity unifies scale-dependent theories of brain function
Analysis of cellular recordings from five phylogenetically diverse species uncovers a conserved, multiscale organization of neuronal activity that resolves disparate theories of brain function. This hierarchical structure allows the brain to operate across multiple timescales, enhances information flow, flexibly reconfigures activity during behavior, and balances functional resiliency with efficiency across scales.
