数据驱动的广义迭代正则化 Landweber 迭代分析

Analysis of Generalized Iteratively Regularized Landweber Iterations driven by data

Andrea Aspri, Otmar Scherzer

AI总结:

本文受数据驱动思想启发,研究广义迭代正则化 Landweber 方法,证明其在线性与非线性不适定问题中的收敛性和稳定性,并通过 Radon 变换数值实验验证。

摘要:

我们研究迭代正则化 Landweber 方法的广义版本,该方法最初由 [Appl. Math. Optim., 38(1):45-68, 1998] 提出,用于求解线性和非线性不适定问题。我们的方法受到 Aspri 等人 [Numer. Funct. Anal. Optim., 41(10):1190-1227, 2020] 引言中强调的数据驱动视角启发。我们给出严格分析,建立了收敛性和稳定性结果,并展示了以 Radon 变换为原型的线性算子数值结果。

英文摘要:

We investigate generalized versions of the Iteratively Regularized Landweber Method, initially introduced in [Appl. Math. Optim., 38(1):45-68, 1998], to address linear and nonlinear ill-posed problems. Our approach is inspired by the data-driven perspective emphasized in the introduction by Aspri et al. [Numer. Funct. Anal. Optim., 41(10):1190-1227, 2020]. We provide a rigorous analysis establishing convergence and stability results and present numerical outcomes for linear operators, with the Radon transform serving as a prototype.
