加权F1 值(Weighted F1) F1 分数是评估模型在二分类任务中预测性能的常用指标,综合考虑了查准率和召回率。F1 分数是查准率和召回率的调和平均值,其取值范围为 0 到 1,其中,1 表示查准率和召回率均达到完美,而 0 则表示查准率和召回率均未达到完美。F1-Score=2×Precision×RecallPrecision+Recall F1 分数有多种...
F1_3 = 2*P3*R3/(P3+R3) = 1 (4)对P1, P2, P3取平均得到P, 对R1, R2, R3取平均得到R, 对F1_1, F1_2, F1_3求平均得到F1: P = (P1+P2+P3)/3 = (1/2 + 0 + 1/3 = 1/2 R = (R1+R2+R3)/3=(1 +0 +1)/3 = 2/3 F1 = 2*P*R/(P+R) = 4/7 4. PRF值-权重(...
FieldMatchWeighted的分数由两部分组成,baseScore和bonusScore,计算公式可以简单表示为:(A*baseScore + bonusScore) / (A + 1)。通过A来调节baseScore所占的比重。baseScore的计算逻辑可以表示为。tw表示term的权重,由查询分析产出,默认为1。bonusScore为加权分数,只有当查询词和字段精确匹配、查询词是字段的一个...

PRF值分别表⽰准确率（Precision）、召回率（Recall）和F1值（F1-score），有机器学习基础的⼩伙伴应该⽐较熟悉。根据标题，先区别⼀下“多分类”与“多标签”：多分类：表⽰分类任务中有多个类别，但是对于每个样本有且仅有⼀个标签，例如⼀张动物图⽚，它只可能是猫，狗，虎等中的⼀种标签（⼆...
