Crowd Comparative Reasoning: Unlocking Comprehensive Evaluations for LLM-as-a-Judge

Qiyuan Zhang, Yufei Wang, Yuxin Jiang +8

LLM-as-a-Judge, which generates chain-of-thought (CoT) judgments, has become a widely adopted auto-evaluation method. However, its reliability is compromised by the CoT reasoning's…
