这种情况下,也就是数据极度不均衡的情况下,micro-f1影响就很大,micro-f1此时几乎只能反映那个类样本量...
“宏查全率”(macro-R)、“宏F1”(macro-F1) 正常最终求得就是“宏F1”
In the classification report, you might be wondering why our micro F1 score of 0.60 is displayed as ‘accuracy’ and why there is NO row stating ‘micro avg’. This is because micro-averaging essentially computes the proportion of correctly classified observations out of all observations. If we...
⑤'weighted': 对每一类别的f1_score进行加权平均,权重为各类别数在y_true中所占比例。 Calculate metrics for each label, and find their average, weighted by support (the number of true instances for each label). This alters ‘macro’ to account for label imbalance; it can result in an F-sco...
