AI Terms Glossary - Accuracy


A machine learning system's accuracy is defined as the proportion of accurate predictions or classifications the model makes over a given data set.

It's usually calculated using a different sample from the one(s) used to build the model, called a test or "hold out" sample.

The error rate, on the other hand, is the percentage of inaccurate predictions on the same data.
