After implementing a model, you find that it has 80 True Positives, 10 False Negatives, 5 False Positives, and 100 True Negatives. What is the recall of the model?
Recall takes into account true positives versus actual positives.
A model shows a confusion matrix with the numbers: TP = 50, TN = 30, FP = 5, FN = 15. If you want to decrease the False Negatives, what strategies can you employ to improve your model?
