Why We Stopped Using Classic Metrics to Evaluate Our LLMs
Traditional NLP metrics like BLEU and ROUGE are insufficient for evaluating generative AI responses in production, especially in complex domains like financial regulatory documentation. These metrics, designed for tasks with single correct answers, fail to capture crucial aspects such as hallucination, usefulness, and trustworthiness. The article proposes using an 'LLM-as-a-Judge' approach, where a capable LLM evaluates responses based on explicit criteria, offering a more nuanced and automated quality assessment. AI
