Predicted category Real category
True head-up rate True head-down
Predicted head-up TP FP
Predicted head-down FN TN

True Positive (TP) The number of positive examples that the model correctly predicts as positive, False Positive (FP) The number of negative examples that the model incorrectly predicts as positive, False Negative (FN) The number of positive examples that the model incorrectly predicts as negative, True Negative (TN) The number of negative examples that the model correctly predicts as negative.
