Mapping Similarity Spaces across Embedding Models with Synthetic Query Probing

Marcin Rozmus, Peter van der Putten

Retrieval-Augmented Generation systems rely on similarity scores to retrieve relevant content, yet scores are not directly comparable across embedding models due to differing geome…

Evaluating Theory of Mind in Reasoning Models: Robustness over Reasoning

Ian B. de Haan, Peter van der Putten, Max van Duijn

Large language models (LLMs) have recently shown strong performance on Theory of Mind (ToM) tests, prompting debate about the nature and validity of the underlying capabilities. At…

Rashomon Alignment

Moisés Santos, Peter van der Putten, Bernhard Pfahringer +1

We propose Rashomon Alignment (RA), a new measure to assess functional similarity between two models. Existing functional similarity measures are distributional, quantifying differ…
