English(EN) When the Right Answer Is Missing: An Arithmetic-Dependent Rejection Bottleneck in Jev

Jev 决策模型在拒绝错误答案时显示出关键瓶颈

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-01 04:00

一篇新的研究论文在 Jev 决策模型中发现了一个显著的、依赖算术的拒绝瓶颈。虽然 Jev 在选择正确的数值答案方面表现出高准确率（99%），但在没有有效选项存在时拒绝错误选项的能力却急剧下降至 7%。这种失败在各种数值大小和问题类型中持续存在，即使模型能够正确验证候选答案也是如此。研究人员提出了一种简单的决策阈值，无需重新训练即可应用，该阈值可将拒绝准确率提高到 79%，同时保持高答案存在准确率。 AI

影响凸显了决策模型中的一个关键缺陷，这可能会影响它们在需要拒绝无效选项的场景中的可靠性。
