MATCHA: Matching Text via Contrastive Semantic Alignment

Siran Li, Ece Sena Etoglu, Carsten Eickhoff +1

Reliable evaluation is essential for understanding large language model (LLM) performance, yet today's go-to metrics, namely token-overlap scores (e.g., ROUGE) and embedding-based…

When Silence Is Golden: Can LLMs Learn to Abstain in Temporal QA and Beyond?

Xinyu Zhou, Chang Jin, Carsten Eickhoff +2

Large language models (LLMs) rarely admit uncertainty, often producing fluent but misleading answers, rather than abstaining (i.e., refusing to answer). This weakness is even evide…

Beyond Multiple Choice: Evaluating Steering Vectors for Summarization

Joschka Braun, Carsten Eickhoff, Seyed Ali Bahrainian

Steering vectors are a lightweight method for controlling text properties by adding a learned bias to language model activations at inference time. While predominantly studied for…
