Andrew Lampinen - Comparing Language Models to Humans: Reasoning & Grammer @ UCL DARK

Invited talk by Andrew Lampinen on March 23, 2023 at UCL DARK. Abstract: Everyone is now talking about Language Models (LMs), and arguing about whether they can reason or produce original content. Is there value in comparing the behavior of language models and humans? And if so, how should we make such comparisons? In this talk, I will draw inspiration from comparative psychology, to suggest that careful methods are needed to ensure that comparisons between humans and models are made fairly, and to highlight an important distinction between LMs and cognitive models that can lead to unfair comparisons. But I will also argue that careful comparisons of LMs to humans offer an opportunity to reconsider our assumptions about the origin and nature of human capabilities. I will illustrate these arguments by focusing on two of our recent papers comparing language models to humans: we find that LMs can process recursive grammar structures more reliably than prior work has suggested (https://arxiv.org/abs/2210.15303), and that LMs show human-like content effects on logical reasoning tasks (https://arxiv.org/abs/2207.07051).
