[GitHub] szha opened a new issue #9588: metric should have TP FP TN FN Precision Recall F1 for both macro and micro versions

szha opened a new issue #9588: metric should have TP FP TN FN Precision Recall F1 for both macro and micro versions
URL: https://github.com/apache/incubator-mxnet/issues/9588
 
 
   Related to #9587. The current logic only supports what's called "macro F1" logic where we take the mean of F1 scores for mini-batches. "micro F1" should also be supported by keeping the tp, fp, fn counts across batches.
   
   Precision and Recall should be added separately.
   5. TopK version of P R F1 should also be supported.
