What does "accuracy" mean in programming?
accuracy is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The degree to which a measurement, prediction, or result reflects the true value. In machine learning, accuracy is the fraction of correct predictions out of all predictions. High accuracy does not always mean a model is useful — check precision and recall too.
Example
"The model has 95% accuracy on the test set, but check precision and recall before shipping to production."
