What does "recall" mean in programming?
recall 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
In machine learning evaluation, the fraction of actual positive cases that a model correctly identifies. A model with high recall misses fewer true positives, though often at the cost of more false positives. Pair with precision to get the full picture.
Example
"Our fraud detection model had 95% recall, meaning it caught 95% of all fraudulent transactions."
