Never Forget Again! // Precision vs Recall with a Clear Example of Precision and Recall

This precision vs recall example tutorial will help you remember the difference between classification precision and recall and why they are sometimes better than accuracy. I show you will a visual example about apples and oranges what each of the three metrics are (precision vs recall vs accuracy). Then I provide you with a helpful tip to remember the definitions of recall and precision. I also visually explain what the precision vs recall tradeoff is and how changing your decision threshold can change both of these metrics for your classification models. Check out this precision vs recall example and never forget again!
