Convergence Analysis of a Two-Point Gradient Method for Nonlinear Ill-Posed Problems
Sprache des Titels:
We perform a convergence analysis of a two-point gradient method which is based on Landweber iteration and on Nesterov's acceleration scheme. Additionally, we show the usefulness of this method via two numerical example problems based on a nonlinear Hammerstein operator and on the nonlinear inverse problem of single photon emission computed tomography.
