Can a grammar book replace training data for AI translation? NYU Linguistics PhD student Jackson Petty (@jacksonpetty.org), CDS Assoc. Prof. Tal Linzen (@tallinzen.bsky.social), and CDS MS student Jaulie Goe tested this with synthetic languages. nyudatascience.medium.com/can-ai-learn...

Can AI Learn a Language from a Textbook?
Most of the world’s 7,000 languages will never have enough written text online to train an AI translation system. However, linguists have…

Linguistics PhD student @jacksonpetty.org finds LLMs "quiet-quit" when instructions get long, switching from reasoning to guesswork. With CDS' @tallinzen.bsky.social, @shauli.bsky.social, @lambdaviking.bsky.social, @michahu.bsky.social, and Wentao Wang. nyudatascience.medium.com/llms-switch-...

I'm hiring at least one post-doc! We're interested in creating language models that process language more like humans than mainstream LLMs do, through architectural modifications and interpretability-style steering. Express interest here: docs.google.com/forms/d/e/1F...

How well can LLMs understand tasks with complex sets of instructions? We investigate through the lens of RELIC: REcognizing (formal) Languages In-Context, finding a significant overhang between what LLMs are able to do theoretically and how well they put this into practice.

@foodnoms.com Can I submit a feature request on bsky? It would be amazing if we could tie Goals to bodyweight, as read in from Apple Health data. Many recommendations for daily protein intake, for instance, are given in grams/kg of bodyweight.

In case it’s of use to other academics, I put together an overleaf project which shows how to use different styles for in-text citations and bibliographies (eg, author-year in text vs numeric in bib). Works in BibLaTeX and hackily in natbib. Link: www.overleaf.com/read/tkxbfty...

How well do LLMs generalize to novel distributions? Our (Michael Wilson Bob Frank) new TACL / EMNLP 2023 paper uses argument structure to test this, finding that LLMs succeed within known contexts but fail to do so between appropriately related ones. 🧵 jacksonpetty.org/argstruct
