Belated, but still happy to see our paper (with @drhanjones.bsky.social) on fleeting memory transformers is out in TACL! We find that giving language models human-like memory decay *improves* language learning, while, unexpectedly, impairing human reading time prediction Follow up results soon!

Wonderful to see this! For (controversial?) context. There’s long been an argument that what brains & ANNs are doing cannot be fathomed beyond the meta like (eg) architecture, learning rules and such. And there’s a counter-idea: ”let’s try?”. When we stumbled on the correlates of memorability /1

What makes some stimuli more memorable than others? In a new paper w/ @davogelsang.bsky.social, we show that the magnitude of a stimulus's ANN representation predicts both image and word memorability Stimuli that activate more features, more strongly, leave a stronger memory trace Out now in JML⬇️

I had the honor of giving a keynote at the International Conference on Machine Learning last week. I addressed the widespread anxiety about how we should adapt as AI capabilities increase. I was thrilled by the talk’s reception, so I have made my slides available www.cs.princeton.edu/~arvindn/tal...

What will be left for us to work on?

Nijmegen friends: Tomorrow (10–12) I'll be debating Pim Haselager at a Donders Session on the thesis: "Artificial neural network models are adequate mechanistic models of the mind" I'm defending, he's opposing. Should be fun. Come join us! www.ru.nl/en/donders-i... @dondersinst.bsky.social

Classic predictive coding: V1 predicts low-level features, higher areas high-level. But recent studies + AI models suggest prediction happens at higher levels of abstraction. Who's right? In new work w/ @wiegerscheurer.bsky.social we find that both are – distinct regimes across the visual field

New preprint! w/ @mheilbron.bsky.social We found that, even during simple natural scene viewing, human visual cortex predicts—hierarchically in central vision and at higher levels peripherally—reconciling classical predictive coding with recent evidence from animal models and AI (e.g. JEPA) (1/10)

What is the relationship between memorization and generalization in AI? Is there a fundamental tradeoff? In infinitefaculty.substack.com/p/memorizati... I’ve reviewed some of the evolving perspectives on memorization & generalization in machine learning, from classic perspectives through LLMs.

Interesting convergence: The trick that made predictive self-supervised vision models work seems to be what the brain was doing all along w/ @predictivebrain.bsky.social: visual cortex is most sensitive to high-level prediction errors -- even in V1 Now published: journals.plos.org/ploscompbiol...

New preprint, w/ @predictivebrain.bsky.social ! we've found that visual cortex, even when just viewing natural scenes, predicts *higher-level* visual features The aligns with developments in ML, but challenges some assumptions about early sensory cortex www.biorxiv.org/content/10.1...

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

Would love to hear expert views on this paper. It appears to show that the operationalization of brain activity the field has relied on for 3 decades—the BOLD response—is not actually a sensible measure of brain activity. www.nature.com/articles/s41...

New preprint! w/@drhanjones.bsky.social Adding human-like memory limitations to transformers improves language learning, but impairs reading time prediction This supports ideas from cognitive science but complicates the link between architecture and behavioural prediction arxiv.org/abs/2508.05803

Human-like fleeting memory improves language learning but impairs reading time prediction in transformer language models

Human memory is fleeting. As words are processed, the exact wordforms that make up incoming sentences are rapidly lost. Cognitive scientists have long believed that this limitation of memory may, para...
