L2 regularization doesn’t perform feature selection, since weights are only reduced to values near 0 instead of 0. L1 regularization has built-in feature selection. L1 regularization is robust to outliers, L2 regularization is not.

WebOverfitting and underfitting are two common problems in machine learning that occur when the model is either too complex or too simple to accurately represent the underlying data. Overfitting happens when the model is too complex and learns the noise in the data, leading to poor performance on new, unseen data.
