What does it mean to understand language? We argue that the brain’s core language system is limited, and that *deeply* understanding language requires EXPORTING info to other brain regions.

Tokenisers are a vital part of LLMs, but how hard is it to find an optimal one? 🤔 Considering arbitrarily large alphabets, prior work showed this is NP-hard. But what if we use bytes instead? Or unary strings like a, aa, aaa, ...? In our new paper, we show this is still hard, NP-hard!

proud to share this work, led by the brilliant @ilinabg.bsky.social, now out in Nature! Ilina finds that speech-sound neural processing is VERY similar in a language you know and one you don't. differences only emerge at the level of word boundaries and learnt statistical structure 🧠✨
The human brain responds to the sounds of both familiar and unfamiliar languages in a similar way, according to research in Nature. The findings might guide future approaches to language learning and rehabilitation. go.nature.com/4ppvsHb #Neuroskyence 🧪
