This paper focuses on the problem of selecting the regularization parameter for linear least-squares estimation. Usually, the problem is formulated as a minimization problem with a cost function consisting of the square sum of the l2 norm of the residual error, plus a penalty term of the squared norm of the solution multiplied by a constant. The penalty… CONTINUE READING
