English(EN) Do Prompt Optimizers Break Requirements They Are Not Scored On? A Preregistered Study

研究发现,提示优化器在未评分的要求上出现回归

一项预注册研究考察了 GEPA、MIPROv2 和 TextGrad 等提示优化器,发现虽然它们在 HotpotQA 等数据集上改进了目标指标,但它们也引入了输出格式和引用有效性等未评分要求的回归。具体来说,在 200 个 token 的输出限制下,相当一部分响应在提供答案之前就被截断了。然而,在更宽松的 1,024 个 token 限制下,这些提取失败被消除,并且在未评分要求上的性能得到了改善。 AI

影响 强调了提示优化中潜在的权衡,建议仔细考虑输出约束和评估指标。
