For example, the following generalization curve suggests overfitting because validation loss ultimately becomes significantly higher than training loss. generalized linear model.When you're doing machine learning, you assume you're trying to learn from data that follows some probabilistic distribution. This means that in any data set, because of randomness, there will be some noise: data will randomly vary. When you overfit, you end up learning from your noise, and including it in your model.

Building machine learning models is a constant battle to find the sweet spot between underfitting and overfitting. The best models will do a good job of generalizing the underlying relationships in the data without modeling the noise in the data. Recognizing Underfitting and OverfittingOverfitting occurs when a statistical model or machine learning algorithm captures the noise of the data. Intuitively, overfitting occurs when the model or the algorithm fits the data too well.
