Imagine you work with images of banknotes. Your task is to predict, if a banknote is forged (F). You've trained a classifier and got first predictions. Now you'd like to compare predicted values with the real ones and calculate the accuracy score of your model.
| True | F | G | F | F | G | F | G | F | F | F |
| Predicted | F | G | G | F | G | G | F | G | F | F |
