A Method for Resolving Ill-conditioned Problems——Two-Step Solution
In this paper, a resolution methods of ill-posed problems based on the Tikhonov regularization theory is studied, and a method of two-step solution is proposed. The purpose of two-step solution is to choose a more appropriate regularizer than that of the ridge estimation. This paper utilizes L-curve method to determine the regularization parameter in the (above) two computation steps.
