The common L1 (Lasso) and L2 (Ridge) regularization methods constrain model complexity and prevent overfitting by adding penalty terms to the loss function.

UnverifiedL1 regularization adds the sum of the absolute values of parameters as a penalty term in the loss function, and its geometric properties cause the optimal solution to tend toward the coordinate axes; L2 regularization adds the sum of squared parameters, penalizing large coefficients without driving them to zero.76% similarUnverifiedLasso回归添加L1惩罚项（权重的绝对值之和），能将不重要特征的系数压缩为零，实现自动特征选择75% similarUnverifiedL2 regularization improves the model's generalization ability by penalizing excessively large weights.73% similarUnverifiedPure Lasso is unstable when facing highly correlated genes, often randomly selecting one gene from a group of correlated genes, while Ridge's L2 penalty allows correlated features to be retained together.72% similarUnverifiedWhen the prior is a Gaussian distribution N(0, σ²I), taking the logarithm transforms the prior term into an L2 norm penalty on the parameters, which is equivalent to the regularization term in ridge regression; a Laplace prior corresponds to an L1 norm penalty, i.e., Lasso regression.71% similar
