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: \(= \dfrac{2 \times \text{precision} \times \text{recall}}{\text{precision} + \text{recall}}\)
