True Positive Classification

A True Positive Classification is a binary classifier positive prediction that is a correct class prediction.

• AKA: TP Outcome.
• Context:
  • It can be a member of a True Positive Classification Set (to calculate a true positive error rate).
  • …
• Counter-Example(s):
  • any False Positive Classification.
  • any True Negative Classification.
  • any False Negative Classification.
• See: True Positive Rate, Confusion Matrix, True Belief.

  • QUOTE: Given a classifier and an instance, there are four possible outcomes. If the instance is positive and it is classified as positive, it is counted as a true positive; if it is classified as negative, it is counted as a false negative. If the instance is negative and it is classified as negative, it is counted as a true negative; if it is classified as positive, it is counted as a false positive. Given a classifier and a set of instances (the test set), a two-by-two confusion matrix (also called a contingency table) can be constructed representing the dispositions of the set of instances.
