As mentioned earlier, 27 samples are correctly predicted to belong to class 1. However, seven samples that are predicted to belong to class 1 actually belong to class 2, two samples belong to class 3, and two samples belong to class 5. For each class, it is possible to evaluate the ...
Precision,Recall,F-measure都有按照不同label分别评价,或者加权总体评价。 但是目前基于DataFrame的好像还没有这么多,没有介绍文档 通过explainParams函数打印出来就四种: System.out.println(evaluator.explainParams()); metricName: metric name in evaluation (f1|weightedPrecision|weightedRecall|accuracy) 1. 2. 使...

To break it down a little, i would expect a recall class bug to have the following characteristics: affects many customers. If only 1 out of 10,000 customers is affected by a bug, well, then it's something that we can wait to fix is a significant problem. If we have a small ...
