Can LLM-as-a-Judge Reliably Verify Rubrics in Agentic Scenarios?

Yangda Peng, Yunjia Qi, Hao Peng +11

Rubric-based scoring has become a widely used paradigm in model evaluation, typically with LLM-as-a-Judge (LaaJ) for rubric scoring. However, the reliability of LaaJ for rubric sco…

WildReward: Learning Reward Models from In-the-Wild Human Interactions

Hao Peng, Yunjia Qi, Xiaozhi Wang +3

Reward models (RMs) are crucial for the training of large language models (LLMs), yet they typically rely on large-scale human-annotated preference pairs. With the widespread deplo…

On the Paradoxical Interference between Instruction-Following and Task Solving

Yunjia Qi, Hao Peng, Xintong Shi +5

Instruction following aims to align Large Language Models (LLMs) with human intent by specifying explicit constraints on how tasks should be performed. However, we reveal a counter…
