saying “no circuits” is like claiming there are no roads in a city, just cars moving around. sure, traffic depends on where people go — but some paths get paved. put differently: meaning may be relational, but some relations — like induction heads and edge detectors —

Our computer vision textbook is now available for free online here: visionbook.mit.edu We are working on adding some interactive components like search and (beta) integration with LLMs. Hope this is useful and feel free to submit Github issues to help us improve the text!

To help computational cognitive scientist engage with more naturalistic experiments, I've made NiceWebRL. NiceWebRL is a Python library for designing human subject experiments that leverage machine reinforcement learning environments. github.com/KempnerInstitu…

🧵 What if two images have the same local parts but represent different global shapes purely through part arrangement? Humans can spot the difference instantly! The question is can vision models do the same? 1/15

In this piece published in The Hill, fellow Turing laureate David Patterson points out that the return on investment of government-funded research in universities is gigantic. Cutting the budgets of NSF and NIH is economic suicide. thehill.com/opinion/techno…

🧵 Can a purely feedforward network — with no recurrence or lateral connections — capture human-like perceptual organization? 🤯 Yes! Especially for contour integration, and we pinpoint the key inductive biases. New paper in PLOS Comp Biol with talia konkle & George Alvarez! 1/24

Excited to share new work with Haemy Lee Masson @hleemasson.bsky.social, Ericka Wodka, Stewart Mostofsky and Leyla Isik! We investigated how simultaneous vision and language signals are combined in the brain using naturalistic+controlled fMRI. Read the paper here: osf.io/b5p4n 1/n

Your pupils don’t just track light. They are a doorway to the dynamics of your entire brain. A new Nature paper shows pupil size alone can reconstruct second-by-second brain activity.

Current theories of consciousness are 'meat-neutral', but if specific physical substrates are necessary, AI may never achieve consciousness. Understanding whether consciousness depends on computational roles, 5/
