Stochastic asymptotical regularization for linear inverse problems

  title={Stochastic asymptotical regularization for linear inverse problems},
  author={Ye Zhang and Chuchu Chen},
We introduce Stochastic Asymptotical Regularization (SAR) methods for the uncertainty quantification of the stable approximate solution of ill-posed linear-operator equations, which are deterministic models for numerous inverse problems in science and engineering. We prove the regularizing properties of SAR with regard to meansquare convergence. We also show that SAR is an optimal-order regularization method for linear ill-posed problems provided that the terminating time of SAR is chosen…

We investigate the method of asymptotical regularization for solving nonlinear ill-posed problems F(x)=y, where, instead of y, noisy data ydelta epsilon Y with //y-ydelta //<or= delta are given and
On the Convergence of Stochastic Gradient Descent for Nonlinear Ill-Posed Problems
Under the canonical tangential cone condition, the regularizing property of the stochastic gradient descent is proved for a priori stopping rules, and convergence rates under suitable sourcewise condition and range invariance condition are established.
Runge–Kutta integrators yield optimal regularization schemes
Asymptotic regularization (also called Showalter's method) is a theoretically appealing regularization scheme for an ill-posed problem Tx = y, T acting between Hilbert spaces. Here, Tx = y is stably
A new class of accelerated regularization methods, with application to bioluminescence tomography
In this paper we propose a new class of iterative regularization methods for solving ill-posed linear operator equations. The prototype of these iterative regularization methods is in the form of

On the interplay of source conditions and variational inequalities for nonlinear ill-posed problems
In the past few years, convergence rates results for Tikhonov regularization of nonlinear ill-posed problems in Banach spaces have been published, where the classical concept of source conditions was
Convergence Rates of First- and Higher-Order Dynamics for Solving Linear Ill-Posed Problems
Recently, there has been a great interest in analysing dynamical flows, where the stationary limit is the minimiser of a convex energy. Particular flows of great interest have been continuous limits
