Maximum entropy method for solving nonlinear ill-posed problems被引量:1
《Chinese Science Bulletin》1996年第19期1589-1593,共5页金其年 侯宗义 
Project supported by the National Natural Science Foundation of China.
We are specially interested in the case that problem (1) is ill-posed; that is, the solutions of (1) do not depend continuously on the data. Now the regularization techniques are required. The traditional method is Ti...

A Kind of a Posteriori Parameter Choices for the Iterated Tikhonov Regularization Method
《Chinese Science Bulletin》1993年第5期356-360,共5页贺国强 
Let X and Y be real Hilbert spaces and A: X→Y be a bounded linear operator with nonclosed range R(A). If y∈ D(A^+)=R(A)+R(A)~⊥, there exists a unique Moore-Penrose generalized solution to the equation Ax=y. In prac...
