Question
For the given confusion matrix, compute the recall True Positive True NegativePredicted Positive 8 3Predicted Negative 2 7 0.73 0.7 0.78 0.8
Solution
The recall (also known as sensitivity or true positive rate) is calculated as the number of true positives divided by the sum of true positives and false negatives.
In this case, the number of true positives (TP) is 8 and the number of false negatives (FN) is 2.
So, the recall is calculated as:
Recall = TP / (TP + FN) = 8 / (8 + 2) = 0.8
So, the recall for the given confusion matrix is 0.8.
