Regularizers

Implements various regularization techniques to constrain model parameters, which helps prevent overfitting.

Regularizer	Abstract base class for regularized solvers.
UnRegularized	Regularizer class for unregularized models.
Ridge	Regularizer class for Ridge (L2 regularization).
Lasso	Regularizer class for Lasso (L1 regularization).
ElasticNet	Regularizer class for Elastic Net (L1 + L2 regularization).
GroupLasso	Regularizer class for Group Lasso (group-L1) regularized models.
