Contrastive ESA: Human Evaluation of Multiple Translations at Once

Vilém Zouhar, Roman Grundkiewicz, Sara Rajaee +6

The paper proposes Contrastive Error Span Annotation (cESA), a human evaluation protocol that shows multiple translations of the same source together, lets annotators mark error sp…

Unlocking Reasoning Capability on Machine Translation in Large Language Models

Sara Rajaee, Sebastian Vincent, Alexandre Berard +3

Reasoning-oriented large language models (RLMs) achieve strong gains on tasks such as mathematics and coding by generating explicit intermediate reasoning. However, their impact on…

Best-of-L: Cross-Lingual Reward Modeling for Mathematical Reasoning

Sara Rajaee, Rochelle Choenni, Ekaterina Shutova +1

While the reasoning abilities of large language models (LLMs) continue to advance, it remains unclear how such ability varies across languages in multilingual LLMs and whether diff…

Local Look-Ahead Guidance via Verifier-in-the-Loop for Automated Theorem Proving

Sara Rajaee, Kumar Pratik, Gabriele Cesa +1

The most promising recent methods for AI reasoning require applying variants of reinforcement learning (RL) either on rolled out trajectories from the LLMs, even for the step-wise…
