需要说明的是,有人[2]列了这样个公式 Fa=(a2+1)PRa2(P+R) 将F-measure一般化. F1-measure认为精确率和召回率的权重是一样的,但有些场景下,我们可能认为精确率会更加重要,调整参数a,使用Fa-measure可以帮助我们更好的evaluate结果. 话虽然很多,其实实现非常轻松,点击此处可以看到我的一个简单的实现. Referen...
a=1 时, F1=FaF_1 = F_aF1=Fa F1-measure认为精确率和召回率的权重是一样的,但有些场景下,我们可能认为精确率会更加重要,调整参数a,使用Fa-measure可以帮助我们更好的evaluate结果. 总结 准确率就是找得对,召回率就是找得全 参考: 准确率(Accuracy), 精确率(Precision), 召回率(Recall)和F1-Measure 准...
