The recall rate is penalized whenever a false negative is predicted. Because the penalties in precision and recall are opposites, so too are the equations themselves. Precision and recall are the yin and yang of assessing the confusion matrix. Recall vs precision: one or the other? As seen be...
A precision-recall curve helps you decide a threshold on the basis of the desirable values of precision and recall. It also comes in handy to compare different model performance by computing “Area Under the Precision-Recall Curve,” abbreviated as AUC. As explained through the confusion matrix,...
for the secret you are the most confident it is indeed a secret. These two naive algorithms are obviously useless. It is combining both precision and recall that is the challenge.
Suppose the spam classifier achieved high Precision and low Recall (Scenario A). This would result in fewer non-spam emails flagged as spam (False Positive). But this would also mean more of the actual spam emails went undetected (False Negative). Conversely, if the classifier achieved high R...
