Hello everyone,
i wrote a function to calculate the sensitivity,specificity, ballance
accuracy and accuracy from a confusion matrix.
Now i have a Problem, I'm getting different values when I'm comparing my
Values with those from the metrics.classification_report function.
The general problem ist, my predicted sensitivity is in the classification
report the precision value. I'm computing every sensitivity with the one
vs all approach. So e.g. Class 1 == true, class 2,3,4,5 are the rest (not
true).
I did this only to get the specificity, and to compare if i computed
everything right.
