Regularization for Ill-Posed EIV Model of Height Anomaly Fitting Based on Generalized Ridge Estimation
Abstract A modified solution for ill-posed EIV model based on regularization matrix, which is established by eigenvector of normal matrix, is proposed in this paper. The modified solution can overcome the weaknesses of algorithms for EIV model. At last, an instance of height anomaly fitting is utilized to verify the feasibility of the presented solution.By comparison with current solutions, the de-regularization and regularization characters of current solutions are also verified.
Key words :
