Precision

Explore how precision evaluates the correctness of positive predictions by comparing true positives to all positive predictions. Understand its importance in minimizing false positives, especially when actions based on predictions are costly. Learn to calculate and interpret precision with scikit-learn to assess model quality effectively.

Introduction

Like the ROC curve, precision is useful over a range of thresholds. Precision is defined as follows:

precision=TPTP+FPprecision = \frac{TP}{TP+FP} ...
