Causally Evaluating the Learnability of Formal Language Tasks

Vésteinn Snæbjarnarson, Anej Svete, Josef Valvoda +3

Language models, as multi-task learners, acquire a wide range of abilities during training. A fundamental question is how much task-specific data is needed to learn a given task. A…

On the Proper Treatment of Units in Surprisal Theory

Samuel Kiegeland, Vésteinn Snæbjarnarson, Tim Vieira +1

Surprisal theory links human processing effort to the predictability of an upcoming linguistic unit, but empirical work often leaves the notion of a unit underspecified. In practic…

Transducing Language Models

Vésteinn Snæbjarnarson, Samuel Kiegeland, Tianyu Liu +3

Modern language models define distributions over strings, but downstream tasks often require different output formats. For instance, a model that generates byte-pair strings does n…

Taxonomy-Aware Evaluation of Vision-Language Models

Vésteinn Snæbjarnarson, Kevin Du, Niklas Stoehr +4

When a vision-language model (VLM) is prompted to identify an entity depicted in an image, it may answer 'I see a conifer,' rather than the specific label 'norway spruce'. This rai…

Gumbel Counterfactual Generation From Language Models

Shauli Ravfogel, Anej Svete, Vésteinn Snæbjarnarson +1

Understanding and manipulating the causal generation mechanisms in language models is essential for controlling their behavior. Previous work has primarily relied on techniques suc…
