Select two best classifier using F1-score,Recall and precision












1














I have three classifiers that classify same dataset with these results:



classifier A:
precision recall f1-score
micro avg 0.36 0.36 0.36
macro avg 0.38 0.43 0.36
weighted avg 0.36 0.36 0.32

classifier B:
precision recall f1-score
micro avg 0.55 0.55 0.55
macro avg 0.60 0.60 0.56
weighted avg 0.61 0.55 0.53

classifier C:
precision recall f1-score
micro avg 0.34 0.34 0.34
macro avg 0.36 0.38 0.32
weighted avg 0.39 0.34 0.32


I want two select two best of them, and I know F1-score is a parameter for compare the classifiers because of its harmony between precision and recall.
So, at first I select classifier B for its best F1-score. for next, both A and C have a same F1-measure,
I want to ask how can I select between them?

          f1-score combines precision and recall in a single figure. As both are pretty similar in A and C cases, f1-score is similar too.



          Your choice depends on what it is less harmful in your categorization: false positives or false negatives.



          I do recommend you to read the 3rd chapter of "DEEP LEARNING:From Basics to Practice" volume 1 by Andrew Glassner. There you have the three concepts (precision, recall and f1-score) described in a very illustrative way.
