generalization curve

A plot of both training loss and validation loss as a function of the number of iterations. A generalization curve can help you detect possible overfitting. For example, the following generalization curve suggests overfitting because validation loss ultimately becomes significantly higher than training loss. See Generalization in Machine Learning Crash Course for more information.

Practitioners refer to generalization curve when building, training, or evaluating machine learning systems. It appears in research papers, product documentation, and technical discussions about AI capabilities and limitations.
