(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(Weighted) weighted计算方法就是对于macro...
多分类的评价指标PRF（Macro-F1MicroF1weighted）详解 也许是由于上学的时候⼀直搞序列标注任务，多分类任务⼜可以简化为简单的⼆分类任务，所以⼀直认为PRF值很简单，没啥好看的。然鹅，细看下来竟有点晦涩难懂，马篇博留个念咯~前⾔ PRF值分别表⽰准确率（Precision）、召回率（Recall）和F1值（F1-...
最后计算 Macro F1, F1A= 0.5, F1B= 0.6, F1C= 0.67, F1D= 0.75, Macro F1 = (F1A+F1B+F1C+F1D)/4 = 0.63. Weighted Average 从计算的角度讲,先对每个类求值,再取平均得到Macro Average会比较容易.但是当数据集中存在严重类别不平衡的问题时,就不适宜单纯使用Macro Average.此时可以采取weighted av...
Macro Average Macro Average会⾸先针对每个类计算评估指标如查准率Precesion，查全率 Recall , F1 Score，然后对他们取平均得到Macro Precesion, Macro Recall, Macro F1. 具体计算⽅式如下：⾸先计算Macro Precesion，先计算每个类的查准率，再取平均： Precesion A＝2/(2+2) = 0.5, Precesion B＝3/(...
The F1 score (aka F-measure) is a popular metric for evaluating the performance of a classification model. In the case of multi-class classification, we adopt averaging methods for F1 score calculation, resulting in a set of different average scores (macro, weighted, micro) in the classificati...
