ExPLAIND: Unifying Model, Data, and Training Attribution to Study Model Behavior

Florian Eichin, Yupei Du, Philipp Mondorf +3

Post-hoc interpretability methods typically attribute a model's behavior to its components, data, or training trajectory in isolation, and are often tied to a particular level of g…

Reasoning that Travels: Dissecting How Chain-of-Thought Transfers Across Models

Xinyuan Cheng, Beiduo Chen, Philipp Mondorf +1

Large reasoning models (LRMs) often generate extensive chain-of-thought (CoT) traces before producing a final answer. As explicit textual artifacts, these traces can be passed to o…

LPDS: Evaluating LLM Robustness Through Logic-Preserving Difficulty Scaling

Philipp Mondorf, Samuel J. Bell, Jesse Dodge +1

As large language models (LLMs) are increasingly deployed to perform tasks with minimal human oversight, it is crucial that these models operate robustly. In particular, a model th…

Tracing Uncertainty in Language Model "Reasoning"

Nils Grünefeld, Bertram Højer, Philipp Mondorf +5

Language model (LM) "reasoning", commonly described as Chain-of-Thought or test-time scaling, often improves benchmark performance, but the dynamics underlying this process remain…

Language Models Learn Universal Representations of Numbers and Here's Why You Should Care

Michal Štefánik, Timothee Mickus, Marek Kadlčík +7

Prior work has shown that large language models (LLMs) often converge to accurate input embedding for numbers, based on sinusoidal representations. In this work, we quantify that t…
