XpertBench：專家級 LLM 基準測試

🔑 增強重點摘要

• •XpertBench utilizes a dynamic 'Difficulty-Weighted Scoring' (DWS) mechanism that adjusts rubric checkpoints based on the historical failure rates of previous SOTA models, preventing score saturation.
• •The benchmark includes a 'Cross-Domain Consistency' metric, which specifically measures if models maintain reasoning integrity when presented with the same logic problem across different professional contexts (e.g., legal vs. medical).
• •The ShotJudge framework incorporates a 'Self-Correction Loop' where the judge model is required to generate a critique of its own initial assessment before finalizing the score, significantly reducing the 'length bias' common in LLM-as-a-judge systems.

🛠️ 技術深入

• •Rubric Architecture: Each task employs a hierarchical rubric structure where 15-40 checkpoints are categorized into 'Core Accuracy,' 'Professional Nuance,' and 'Regulatory Compliance'.
• •ShotJudge Implementation: Utilizes a 5-shot prompt template containing high-variance examples (correct, incorrect, and partially correct) to calibrate the judge model's latent scoring distribution.
• •Bias Mitigation: Employs a 'Position-Balanced' evaluation strategy where the judge evaluates the model output in both original and reversed order to mitigate positional bias.
• •Data Integrity: The dataset is hosted on a version-controlled repository with a 'Contamination-Detection' layer that cross-references task prompts against common pre-training corpora (e.g., Common Crawl, Pile) to ensure zero-shot validity.
