WebDec 12, 2024 · One way to prevent overfitting is to use regularization. Regularization is a technique that adds a penalty to the model for having too many parameters, or for having parameters with large values. This penalty encourages the model to learn only the most important patterns in the data, which can help to prevent overfitting.
