实验指标:
- TP: True Positive, 正确且召回
- FP: False Positive, 错误但召回
- FN: False Negative, 错误未召回
- TN: True Negative, 正确未召回
衍生指标:
- precision: $ = \dfrac{TP}{TP+FP}$
- recall: \(= \dfrac{TP}{TP+FN}\)
-
accuracy: \(= \dfrac{TP+TN}{TP+FN+TN+FP}\)
-
EM: exact match, 衡量预测值与答案是否一致
-
F1: \(= \dfrac{2 \times \text{precision} \times \text{recall}}{\text{precision} + \text{recall}}\)
