Preference Leakage: A Contamination Problem in LLM-as-a-judge

ICLR 2026poster

Large Language Models (LLMs) as judges and LLM-based data synthesis have emerged as two fundamental LLM-driven data annotation methods in model development. While their combination significantly enhances the efficiency of model training and evaluation, little attention has been given to the potentia…

From Generation to Judgment: Opportunities and Challenges of LLM-as-a-judge

EMNLP 2025

Assessment and evaluation have long been critical challenges in artificial intelligence (AI) and natural language processing (NLP). Traditional methods, usually matching-based or small model-based, often fall short in open-ended and dynamic scenarios. Recent advancements in Large Language Models (LL

Large Language Models for Data Annotation and Synthesis: A Survey

EMNLP 2024main

Data annotation and synthesis generally refers to the labeling or generating of raw data with relevant information, which could be used for improving the efficacy of machine learning models. The process, however, is labor-intensive and costly. The emergence of advanced Large Language Models (LLMs),…
