A 3.5-month-old knows that a ball rolling behind a wall is still there. Today we're releasing a full-stack data infrastructure to teach object permanence to AI: 🧠 150 cognitive tasks scaling to 10K+ diverse samples 📦 A 1.5M-sample training set 🚀 A fine-tuned 16B model that validates the data

This should be fun! I'll be talking about what it means for a neural network to have a world model (joint work with @raphaelmilliere.com) and presenting new evidence that the standard example, Othello-GPT, does not have one (joint work with @shauli.bsky.social among others).

Do LLMs *understand* language? Do educational AI agents *understand* the material they teach (or their students)? Claims about what AI systems do or don't understand are pervasive, but assessing them requires an account of MACHINE UNDERSTANDING

This talk will be 🔥. It should be of special interest to philosophers because of its implications for the overflow debate about consciousness. Gal won't have time to talk about those implications on Monday, but she'll be happy to talk about them after. Hope to see you there!

5 years since our first pilot, and 25,000 participants later, I'm super happy this work with Makaela Nartker, @chazfirestone.bsky.social and Howard Egeth on inattentional blindness is now out in eLife! A little 🧵 of what we found... 1/12 elifesciences.org/articles/100...

Sensitivity to visual features in inattentional blindness
As a group, inattentionally blind participants can successfully report the location, color, and shape of stimuli they deny noticing, and exhibit a systematic bias to report not noticing.

For example, that all cognition should be modeled as dynamic coupling with the environment, without any need for internal representations.

I think of it as a spectrum of views that range from the obvious to the absurd. Its proponents typically describe a handful of examples that support views on the obvious end and then claim to have established one of the views on the absurd end.

I think the latest cuts will save ~$2m. It's hard to know how helpful this will be -- they haven't given us any financial details. They have minimized the faculty's role in all aspects of the college, including oversight of the budget.

On a more optimistic note, I just want to say that I'm incredibly proud of the reporting by our students at the Spectator. They are a consistent source of balanced and informed reporting about all issues, large and small.

The crisis at Barnard is at least partly because Columbia is trying to solve its own budgetary problems by forcing Barnard to contribute more. This year, it has to contribute ~$12m in addition to its usual contribution of ~$10m.
