Are Precision and Recall Interdependant

#1

Are precision and recall inversely or directly dependent on each other??
Like… if we increase the precision… What will the impact on recall?

  1. Decreses
  2. Increases
  3. Can decrese or increase (does not have any impact)

Hi @satyadeep9123,

Have a look at the confusion matrix :

Precision : The total actual positive cases versus number of positives predicted.

Recall : Total actual positives versus the number of correct predictions.

As precision increases, the recall should decrease. Have a look at the precision-recall tradeoff curve to understand it better
