I am working on a binary classification using random forest with 977 records with 77:23 class proportion
I got the below performance in train and test data (AUC = 81)
My metric of interest is
F1-score because my dataset is imbalanced.
So, based on the above classification report, we can infer that drop in
F1-score is not huge between train and test. Am I right to understand that?
How much is considered a huge drop?
Should I be worried about Precision and Recall values being dropped heavily? I don't assess my model based on precision and recall indvidually. Should I just focus on
F1 and conclude whether my model is overfit or not? Or all the metrics should have some decent/gradual drop?
If we see
1.00 for any of the metric, is it sure shot way to say that model is overfitting?
update - new run screnshot - 7 point drop in f1-score
