Cosyne Viewing Parties

Visas, costs, care responsibilities, and environmental concerns all limit Cosyne attendance. Luckily, the talks are livestreamed; but watching alone is the high road to an aneurism. Hence: viewing parties! Gather regionally to watch Cosyne talks! More info: shorturl.at/3DHZX.

In this piece for @thetransmitter.bsky.social, I argue that ecological neuroscience should leverage generative video and interactive models to simulate the world from animals' perspectives.

The technological building blocks are almost here - we just need to align them for this application.

This work has been accepted to #COLM2025. If you are in Montreal this week for COLM and would like to chat about this (or anything related to discovery / exploration / RL), drop me a note!

Insights from the Algonauts 2025 Winners What did we learn from a contest to predict fMRI brain activity to movie viewing?

Nice write-up on the top-performing models of Algonauts 2025 competition by @humanscotti.bsky.social

paulscotti.substack.com/p/insights-f...

None of the teams trained the models from scratch, mainly relied on pre-trained foundation models, and ensembling seemed to be the key ingredient.

Levine's take on the success of LLMs compared to video models is interesting, but I'll expand on how efforts toward AI could take two different paths, and why I think AI and NeuroAI could take different approaches moving forward. 🧡

Can babies inspire more efficient learning algorithms? A competition that trains language models on smaller datasets, more akin to how a baby learns, seeks solutions to some of LLM’s major challenges.

New work: AI agents learn from adult data, inheriting our biases when making decisions. What if we trained them to think like kids, who rigorously explore and make causal inferences?

Fascinating preprint from with our "blicket detector" paradigm from Chen et al at NYU& Mila. LLM's make the same causal inference mistakes that adults make but 4 year olds don't! Of course, models are trained on adult data, kids figure it out for themselves.

Preprint Alert πŸš€

Can we simultaneously learn transformation-invariant and transformation-equivariant representations with self-supervised learning?

TL;DR Yes! This is possible via simple predictive learning & architectural inductive biases – without extra loss terms and predictors!

on my way back to NYC, i met wise Leon Bottou in the airport. we talked. then i told him "you should tweet that!"

and, he delivered much more than a tweet: a blog post with thoughts and insights on AI research only he can deliver this clearly and succinctly.

Top-down feedback matters: Functional impact of brainlike connectivity motifs on audiovisual integration

Top-down feedback is ubiquitous in the brain and computationally distinct, but rarely modeled in deep neural networks. What happens when a DNN has biologically-inspired top-down feedback? πŸ§ πŸ“ˆ

To my Canadian colleagues: you should know that a key component of what the US is doing right now involves purging scientists & research programs for ideological impurity & (illegally) reclaiming their funds.

Depends on the school… some in-person schools eg. Imbizo put in huge amount of resources for each individual student to warrant a letter

Can LLMs be used to discover interpretable models of human and animal behavior?πŸ€”

Turns out: yes!

Thrilled to share our latest preprint where we used FunSearch to automatically discover symbolic cognitive models of behavior.

Delighted to be in Leeds joining the School of Computing! Fantastic first impressions β€” like a "less offensive London" (youtu.be/watch?v=_6_VVLgrgFI). Stay tuned for a PhD position starting next October. Meanwhile, drop me a message with your CV and research interestsβ€”I'd love to hear from you!

Neuroscience is starting to grow past relying on single neuron selectivity to understand computations, now that we have more data and better analyses. This could have interesting implications for mechanistic interpretability in AI models as well!

Searching for Rewards Like a Child Means Less Generalization and More Directed Exploration - Eric Schulz, Charley M. Wu, Azzurra Ruggeri, BjΓΆrn Meder, 2019 How do children and adults differ in their search for rewards? We considered three different hypotheses that attribute developmental differences to (a) children...

There's plenty of evidence that suggest children explore better than adults, eg. journals.sagepub.com/doi/abs/10.1..., which seems useful for RL (eg. openreview.net/forum?id=5uU...)
