A table layout that shows the results of a two-class/binary classifier in which columns correspond to the predicted classifications from the model and rows correspond to the observed classifications.
Note: A confusion matrix highlights the numbers of true positives TP (positives classified as positive), true negatives TN (negatives classified as negative), false positives FP (negatives classified as positive) and false negatives FN (positives classified as negatives).
