**Get Machine Learning Recall Gif**. Let's calculate precision for our ml model from the previous sectionthat analyzes tumors: What is precision and recall?

Imagine the classification has three targets named “a”, “b”, and “c” skewed with 200, 30, and 20 records. See full list on analyticsvidhya.com Precision is the ratio of true positivesto the total of the true positives and false positives.

### True negative rate (tnr) or the specificity:

So, four types of classes can be recognized. See full list on medium.com Most of the time we want to set figure out how to set precision value and recall value. For our model, recall = 0.86.
