Bi-matching f1 score
WebSo, in my case, the main difference between the classifiers was reflected on how well they perform on f1-score of class 1, hence I considered f1-score of class 1 as my main evaluation metric. My secondary metric was PR-AUC, again, on class 1 predictions (as long as my classifiers keep performing pretty well on class 0, and they all did).
