Description: A regularization parameter is a fundamental tool in the field of machine learning, especially in the context of AutoML, used to prevent model overfitting. Overfitting occurs when a model fits too closely to the training data, capturing noise and irrelevant patterns, resulting in poor performance on unseen data. To mitigate this issue, a penalty for model complexity is introduced during the training process. This penalty can be implemented in various ways, such as through L1 (Lasso) and L2 (Ridge) regularization techniques, which add a term to the model’s cost that penalizes the coefficients of the features. In this way, the goal is to find a balance between model accuracy and complexity, favoring simpler solutions that generalize better to new data. Regularization not only improves model robustness but can also help identify relevant features by reducing the impact of those that are less significant. In the context of AutoML, where processes of model selection and tuning are automated, regularization becomes an essential component for optimizing the performance and efficiency of machine learning models.
