What is the False Positive Rate?
The False Positive Rate (Fall-out) is a performance metric that measures the probability that your model will predict positive when the true value is negative.
- It is closely related to the False Negative Rate, which is completely analogous.
- The False Positive Rate and the True Negative Rate sum up to 1.
- The False Positive Rate is the answer to the following question: “If the true value is negative, what share did my model predict incorrectly?”
- The False Positive Rate is calculated as follows:
