What is the Difference Between AUC and Accuracy?

The AUC formula measures the area under a receiver operating characteristic (ROC) curve, which plots the true positive rate against the false positive rate at different thresholds. The formula calculates the average area under the ROC curve, providing a single value that represents the model's ability to distinguish between positive and negative classes. Think of it as a measure of a model's confidence in its predictions.

Yes, the AUC formula can be used with various machine learning algorithms, including decision trees, random forests, and support vector machines.
