New work to appear @ TACL! Language models (LMs) are remarkably good at generating novel well-formed sentences, leading to claims that they have mastered grammar. Yet they often assign higher probability to ungrammatical strings than to grammatical strings. How can both things be true? 🧵👇

Screenshot of a figure with two panels, labeled (a) and (b). The caption reads: "Figure 1: (a) Illustration of messages (left) and strings (right) in toy domain. Blue = grammatical strings. Red = ungrammatical strings. (b) Surprisal (negative log probability) assigned to toy strings by GPT-2."

Me and @wegotlieb.bsky.social were recently invited to write a wide-ranging reflection on the current state of linguistic theory and methodology. A draft is up here. For anyone interested in thinking big about linguistics, we'd be happy to hear your thoughts! arxiv.org/abs/2502.18313 #linguistics

Looking forward: Linguistic theory and methods

This chapter examines current developments in linguistic theory and methods, focusing on the increasing integration of computational, cognitive, and evolutionary perspectives. We highlight four major ...
