How to know if model is overfitted
Web10 mrt. 2024 · In particular, the re-substitution loss of an overfitted model is smaller than the loss if the model is applied to the data the model does not learn. Therefore, the re-substitution loss overestimates the actual model performance and is inappropriate for evaluating the model performance.
