I am working on binary classification for classifying cancer=1 and no-cancer=0, I use confusion matrix from sklearn, this is my confusion matrix on test set:
# confusion matrix [[18 0] [ 7 15]] # in my reading the order is: TN=18 FP=0 FN=7 TP=15
but in some tutorials, I see different ordering for FP and FN, some said same as my reading,See here, but other said reverse of FP and FN, see here. my question is which one is true in my case? please give me a reference to be sure about the answer.
