  • Step 1: Determine the True Positive Rate

      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.

    The AUC formula offers several opportunities, including:

  • Divide the number of false positives by the total number of actual negative instances
  • Step 3: Plot the ROC Curve
    • Calculate the number of false positives and true negatives
    • Overfitting: Models may overfit to the training data, leading to poor performance on new, unseen data.
