Related Terms

ROC Curve related to

Plots true positive rate vs false positive rate across thresholds; summarizes separability.

 AUC related to

Scalar summary of ROC; measures ranking ability, not calibration.

 Calibration related to

The degree to which predicted probabilities match true frequencies (e.g., 0.8 means ~80% correct).

 Stochastic Gradient Descent related to

A gradient method using random minibatches for efficient training on large datasets.

 Accuracy related to

Fraction of correct predictions; can be misleading on imbalanced datasets.

 Precision related to

Of predicted positives, the fraction that are truly positive; sensitive to false positives.

 Recall related to

Of true positives, the fraction correctly identified; sensitive to false negatives.

 Specificity related to

Of true negatives, the fraction correctly identified.
