Sure I will

Actually only the diagonal elements are the correctly predicted values right?

[@MaheshHuddar]

Yes
You are right

[@tovideo100]

Thank you, sir. How can we calculate overall precision, recall, and F1 score from the confusion matrix that you have explained?

[@davimisturini8922]

he explained at the end of the video when calculated the macro f1 score (this is the "overall f1 score" that you said). Just calculate the metrics for each class and then take the mean.

[@taniadas3301]

Can you please explain formula for weighted precision

[@NehaRana-z4y]

What is the accuracy of the classifier?

[@mehrmalik5860]

Kindly tell us formula for weighted F1 the way you wrote for Macro F1 . thanks
