Igniters, Alexey I want to discuss the ticket 10371 [1], currently, we calculate 4 numbers (true positive, true negative, false positive, false negative) for each "point metric" like accuracy, recall, f-score and precision for each label.
So for the full score we need calculates those 4 numbers 8 times. But we could calculate all 8 metrics(4 for the first label and 4 for the second label). I suggest introducing new API "point metric" for metrics like those 4(accuracy, recall, f-score, and precision) and "integral metric" for metrics like ROC AUC [2]. Any thoughts would be appreciated.
