提示词优化陷阱:准确率 vs. AUROC 以获得更好的 LLM 性能

一种仅依赖准确率的提示词优化技术可能导致模型无效,尤其是在数据集不平衡的情况下。作者解释说,提示词优化器(如 DSPy)本质上是爬山算法,它们针对给定的标量指标进行优化,如果优先考虑准确率而不是排名行为等其他因素,这可能会产生误导。一篇论文被重点介绍,该论文提出了一种通过在评估中使用正负样本对将优化目标从准确率更改为 AUROC(接收者操作特征曲线下面积)的方法,这更好地反映了排名很重要的实际部署场景。 AI

影响 强调了为提示词优化选择适当指标的重要性,以确保 LLM 在实际应用中的有效性。

    提示搜索是爬坡算法,而准确性是错误的山坡

    <p>I once shipped a prompt that scored 0.94 on my eval set and was useless in triage. Not wrong, exactly. Just useless — it ranked the one case I needed to see at position nine, behind eight things that were fine.</p> <p>That's the whole article, really. But the mechanism is wort…
