The notion of regularization has been widely used as a tool to address a number of problems that are usually encountered in Machine Learning. Improving the performance of an estimator by shrinking the norm of the MVU estimator, guarding against overfitting, coping with ill-conditioning, providing a solution to an underdetermined set of equations, are some notable examples where regularization has provided successful answers. A notable example is the ridge regression concept, where the LS loss… CONTINUE READING
