Task-optimized models of sensory uncertainty reproduce human confidence judgments
Sensory input is often ambiguous, leading to uncertain interpretations of the external world. Estimates of perceptual uncertainty might be useful in guiding behavior, but it remains unclear whether hu...

We also wondered: if neuroscientists use functional localizers to map networks in the brain, could we do the same for MiCRo’s experts?
The answer: yes! The very same localizers successfully recovered the corresponding expert modules in our models!

🚀 Excited to share a major update to our “Mixture of Cognitive Reasoners” (MiCRo) paper!
We ask: What benefits can we unlock by designing language models whose inner structure mirrors the brain’s functional specialization?

Check out @mryskina.bsky.social's talk and poster at COLM on Tuesday—we present a method to identify 'semantically consistent' brain regions (responding to concepts across modalities) and show that more semantically consistent brain regions are better predicted by LLMs.
Interested in language models, brains, and concepts? Check out our COLM 2025 🔦 Spotlight paper!
(And if you’re at COLM, come hear about it on Tuesday – sessions Spotlight 2 & Poster 2)!

Do you want to use AI models to understand human language?
Are you fascinated by whether linguistic representations are lurking in LLMs?
Are you in need of a richer model of spatial words across languages?

LLMs trained on next-word prediction (NWP) show high alignment with brain recordings. But what drives this alignment—linguistic structure or world knowledge? And how does this alignment evolve during training? Our new paper explores these questions. 👇🧵

Humans largely learn language through speech. In contrast, most LLMs learn from pre-tokenized text.
In our #Interspeech2025 paper, we introduce AuriStream: a simple, causal model that learns phoneme, word & semantic information from speech.
