Approximate solution of nonlinear inverse problems by fixed-point iteration
In this paper we propose a derivative-free iterative method for the approximate solution of a nonlinear inverse problem Fx = y. In this method the iterations are defined as Gxk+1 = Gxk +(Sy−SFxk), where G is an easily invertible operator and S is an operator from a data space to a solution space. We give general suggestions for the choice of operators G and S and show a practically relevant exa...
متن کاملRegularized Fixed-Point Iterations for Nonlinear Inverse Problems
In this paper we introduce a derivative-free, iterative method for solving nonlinear illposed problems Fx = y, where instead of y noisy data yδ with ‖y − yδ‖ ≤ δ are given and F : D(F ) ⊆ X → Y is a nonlinear operator between Hilbert spaces X and Y . This method is defined by splitting the operator F into a linear part A and a nonlinear part G, such that F = A + G. Then iterations are organized...

متن کاملA Nonlinear Solution of Inverse Problems
We consider here a classical problem of estimating or approximating a density given the information consisting of the values of some of its integrals. The method will have direct applications in many problems of density, spectral density and image analysis which will not be treated in any detail here. One widely used method chooses the density which minimizes a cross entropy functional. We prop...
