Research on Applied Technology in Comparison of the Traditional Inversion Method and the AIC Method

Abstract

Regularization item, subject to data misfit is used to stabilize the inversion problem. In selection of the trade-off parameter the Akaiche Information Criterion (AIC) has been applied to and compared to the chi-square misfit criterion. For the AIC we can achieve the trade-off parameter more conveniently by minimizing the AIC fuction. The result shows the AIC works well with an agreement to one accomplished from the Chi-square method. The result is very meaningful about applied technology of ocean science and geophysics.
