What Does True Positives Mean?

True positives as results in machine learning classification problems involve outputs where a test observes a positive, where a positive was also predicted. This is part of the classical confusion matrix that engineers use as a model for discussing a classifying algorithm.

For example, a classifying algorithm might be asked to identify cats and dogs in a set of initial test data. The values of the test data are known beforehand, so engineers can compare the known classifications to what the system predicts or classifies.
