True positives (TP), true negatives (TN),
false positives (FP), and false negatives
(FN), are the four different possible outcomes of a single prediction
for a two-class case with classes “1” (“yes”) and “0” (“no”). A
false positive is when the outcome is incorrectly
classified as “yes” (or “positive”), when it is in fact “no” (or
“negative”). A
false negative is when the outcome is incorrectly
classified as negative when it is in fact positive.
True positives and true negatives are
obviously correct classifications.
