True Positive (TP)

What is a True Positive (TP)?

When evaluating the prediction of a model given a sample, a True Positive (TP) is the outcome where the model correctly predicts the positive class.

Consider the example of a model which classifies emails as either spam (positive class) or not spam (negative class). If the actual label of the sample is spam and the model correctly predicts spam then this outcome will be considered a True Positive.
