Convergence analysis of a stochastic heavy-ball method for linear ill-posed problems (2406.16814v1)
Published 24 Jun 2024 in math.NA, cs.NA, and math.OC
Abstract: In this paper we consider a stochastic heavy-ball method for solving linear ill-posed inverse problems. With suitable choices of the step-sizes and the momentum coefficients, we establish the regularization property of the method under {\it a priori} selection of the stopping index and derive the rate of convergence under a benchmark source condition on the sought solution. Numerical results are provided to test the performance of the method.
