True Negative

定义 Definition(中文)

True negative(真阴性):在诊断检测或分类任务中,模型/测试判断为“阴性/否”,且真实情况也确实为“阴性/否”的结果。常用于混淆矩阵与医学检验评估中(与真阳性、假阳性、假阴性并列)。

发音 Pronunciation(IPA)

/tru ntv/

例句 Examples

The test result was a true negative, so the patient does not have the disease.
检测结果为真阴性,因此患者没有这种疾病。

In a large screening program, a high number of true negatives can still hide the problem of many false negatives.
在大规模筛查中,即使真阴性的数量很高,也可能掩盖“假阴性”较多的问题。

词源 Etymology(中文)

该术语由 true(真实的、正确的)negative(阴性;否定的) 组合而成。它源自统计学与医学检验的判定框架,用“true/false”表示判断是否正确,用“positive/negative”表示检测结果为阳性或阴性(或分类为是/否)。
