Curves obtained in the F-measure space are compared to those of existing spaces (ROC, precision-recall and cost) and analogously to cost curves. The proposed F-measure space allows to visualize and compare classi-fiers' performance under different operating conditions more easily than in ROC and...
大多情况算数平均都可以使用,因为我们都假设有线性关系存在,譬如说平均距离;几何平均常用于人口计算,因为人口增加是成比例增加的;调和平均常用于计算平均速率,在固定距离下,所花时间就是平均速率,这数据成倒数关系,而F1 Measure也同样是这样的数据特性,在固定TP的情况下,有不同的分母,所以这里使用调和平均较为适当。
