New preprint, w/ Karolina Drożdż Understanding language requires internally modelling what's happening where, even when unstated We built a new task to measure this ability in language models and people, and find it emerges at model scales far smaller than previously thought

@arthurpr4t.bsky.social has a new preprint with important results on a famous psychophysical law (Weber's law). It isn't, in fact, a law, because it can be broken. A more fundamental principle (efficient coding) shows when and why Weber's law holds true. www.biorxiv.org/content/10.6...

Why do we breeze through some sentences, but others make us slow down and reread? A popular answer is predictability: unexpected words are harder to process. In our new @pnas.org article, we used LMs as models of human prediction to ask how far this explanation can actually go🧵

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⬇️

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

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!
