Judge Circuits

Nils Feldhus, Tanja Baeumel, Elena Golimblevskaia +10

LLM-as-a-judge has become the dominant paradigm for grading model outputs at scale, yet the same model assigns systematically different scores when its output format changes (e.g.,…

Parallel Universes, Parallel Languages: A Comprehensive Study on LLM-based Multilingual Counterfactual Example Generation

Qianli Wang, Van Bach Nguyen, Yihong Liu +6

Counterfactuals refer to minimally edited inputs that cause a model's prediction to change, serving as a promising approach to explaining the model's behavior. Large language model…

Guiding LLMs to Generate High-Fidelity and High-Quality Counterfactual Explanations for Text Classification

Van Bach Nguyen, Christin Seifert, Jörg Schlötterer

The need for interpretability in deep learning has driven interest in counterfactual explanations, which identify minimal changes to an instance that change a model's prediction. C…

Truth or Twist? Optimal Model Selection for Reliable Label Flipping Evaluation in LLM-based Counterfactuals

Qianli Wang, Van Bach Nguyen, Nils Feldhus +4

Counterfactual examples are widely employed to enhance the performance and robustness of large language models (LLMs) through counterfactual data augmentation (CDA). However, the s…

LLMs for Generating and Evaluating Counterfactuals: A Comprehensive Study

Van Bach Nguyen, Paul Youssef, Christin Seifert +1

As NLP models become more complex, understanding their decisions becomes more crucial. Counterfactuals (CFs), where minimal changes to inputs flip a model's prediction, offer a way…
