A Cross-Linguistic Pressure for Uniform Information Density in Word Order

Thomas Hikaru Clark, Clara Meister, Tiago Pimentel +4

While natural languages differ widely in both canonical word order and word order flexibility, their word orders still follow shared cross-linguistic statistical patterns, often at…

A Theory of Emergent In-Context Learning as Implicit Structure Induction

Michael Hahn, Navin Goyal

Scaling large language models (LLMs) leads to an emergent capacity to learn in-context from example demonstrations. Despite progress, theoretical understanding of this phenomenon r…

Sensitivity as a Complexity Measure for Sequence Classification Tasks

Michael Hahn, Dan Jurafsky, Richard Futrell

We introduce a theoretical framework for understanding and predicting the complexity of sequence classification tasks, using a novel extension of the theory of Boolean function sen…

RNNs can generate bounded hierarchical languages with optimal memory

John Hewitt, Michael Hahn, Surya Ganguli +2

Recurrent neural networks empirically generate natural language with high syntactic fidelity. However, their success is not well-understood theoretically. We provide theoretical in…

Wreath Products of Distributive Forest Algebras

Michael Hahn, Andreas Krebs, Howard Straubing

It is an open problem whether definability in Propositional Dynamic Logic (PDL) on forests is decidable. Based on an algebraic characterization by Bojańczyk, et. al.,(2012) in term…

Tabula nearly rasa: Probing the Linguistic Knowledge of Character-Level Neural Language Models Trained on Unsegmented Text

Michael Hahn, Marco Baroni

Recurrent neural networks (RNNs) have reached striking performance in many natural language processing tasks. This has renewed interest in whether these generic sequence processing…
