How to judge overfitting
WebThe first is the most straightforward: overfitting on the training set. This means that the model has memorized the training set and can't generalize beyond that. If the test set … Web23 aug. 2024 · We can identify overfitting by looking at validation metrics, like loss or accuracy. Usually, the validation metric stops improving after a certain number of epochs and begins to decrease afterward. The training metric continues to improve because the model seeks to find the best fit for the training data.
