It is the amount of information transmitted by a number. It shows the proximity of two or more dimensions to each other. It is independent of accuracy.
The concepts of Accuracy and Precision are closely related, and it is easy to confuse.
Precision amount of information transmitted by value. Although accuracy is an accurate measure of the value associated with information.
Let us consider the value of "pi", i.e., 3.142857143. Where 3.14 is considered precise, and 3.1428527143 is considered accurate.
A precision calculation formula is provided by:
Example
The binary model makes predictions and predicts 160 samples as class A, 105 positive, and 55 negative. Calculate the precision of this model.
