# Trade-offs and Curves

Learn about receiver operating characteristic (ROC) and precision-recall (PR) curves. And take a look at how lowering or increasing thresholds affects the results.

## We'll cover the following

## Introduction to ROC and PR curves

We already know there are trade-offs between true and false-positive rates as well as between precision and recall. We also know that there are many confusion matrices, one for each threshold. What if we were to combine these two pieces of information?

We present to you the receiver operating characteristic (ROC) and precision-recall (PR) curves! Well, they are not curves *yet*, but they will be soon enough.
