   Precision and Recall are the two most important but confusing concepts in Machine Learning. Precision and recall are performance metrics used for pattern recognition and classification in machine learning. These concepts are essential to build a perfect machine learning model which gives more precise and accurate results.

   Precision shows how often an ML model is correct when predicting the target class. Recall shows whether an ML model can find all objects of the target class. Consider the class balance and costs of different errors when choosing the suitable metric.

   Probabilistic Definition. Precision and recall can be interpreted as (estimated) conditional probabilities: Precision is given by (= | ^ =) while recall is given by (^ = | =), where ^ is the predicted class and is the actual class (i.e. = means the actual class is positive).

   What does recall mean in ML?

   • In common English, recall means to remember something; in ML it means how many hits the model picked up out of the possible correct items. Perhaps hit% would have been a better nomer. Recall literally is how many of the true positives were recalled (found), i.e. how many of the correct hits were also found.

   What does recall mean?

   • By definition recall means the percentage of a certain class correctly identified (from all of the given examples of that class). So for the class cat the model correctly identified it for 2 times (in example 0 and 2). But does it mean actually there are only 2 cats? No! In reality there are 3 cats in the ground truth (human labeled).
