Adapting Language Models to Compress Contexts

Alexis Chevalier, Alexander Wettig, Anirudh Ajith +1

Transformer-based language models (LMs) are powerful and widely-applicable tools, but their usefulness is constrained by a finite context window and the expensive computational cos…

Piecewise Interpretable Hilbert Spaces

Alexis Chevalier, Ehud Hrushovski

We study Hilbert spaces interpreted, in an appropriate sense, in a first-order theory. Under a new finiteness hypothesis that we call {\em scatteredness} we prove that is a…

Model Theory of Scattered Piecewise Interpretable Hilbert Spaces

Alexis Chevalier

We study scattered piecewise interpretable Hilbert spaces from a model theoretic point of view. We establish strong connections between the Hilbert space structure theorems of [Che…

Language Models as Science Tutors

Alexis Chevalier, Jiayi Geng, Alexander Wettig +19

NLP has recently made exciting progress toward training language models (LMs) with strong scientific problem-solving skills. However, model development has not focused on real-life…

An Algebraic Hypergraph Regularity Lemma

Alexis Chevalier, Elad Levi

Szemerédi's regularity lemma is a powerful tool in graph theory. It states that for every large enough graph, there exists a partition of the edge set with bounded size such that…

Mathematical Capabilities of ChatGPT

Simon Frieder, Luca Pinchetti, Alexis Chevalier +5

We investigate the mathematical capabilities of two iterations of ChatGPT (released 9-January-2023 and 30-January-2023) and of GPT-4 by testing them on publicly available datasets,…
