On the randomized kaczmarz algorithm
WebThe Kaczmarz method, or the algebraic reconstruction technique (ART), is a popular method for solving large-scale overdetermined systems of equations. Recently, Strohmer et al. proposed the randomized Kaczmarz algorithm, an improvement that guarantees exponential convergence to the solution. This has spurred much interest in the … WebRandomized Kaczmarz (RK), Motzkin Method (MM), and Sampling Kaczmarz Motzkin (SKM) algorithms are commonly used iterative …

WebThe Kaczmarz method in [2] is possible one of the most popular, simple while efficient algorithms for solving (1). It was revised to be applied to image reconstruction in [3], which is called algebraic reconstruction technique, and has a large range of fields of applications such as image reconstruction in computerized tomography [4] [5] [6] and parallel … WebIn this work, we propose a novel algorithmic framework based on the Kaczmarz algorithm for tensor recovery. We provide thorough convergence analysis and its applications from …
WebStochastic gradient descent, weighted sampling, and the randomized Kaczmarz algorithm. Pages 1017–1025. Previous Chapter Next Chapter. ABSTRACT. We improve a recent guarantee of Bach and Moulines on the linear convergence of SGD for smooth and strongly convex objectives, reducing a quadratic dependence on the strong convexity to a linear ... Webrandomized Kaczmarz method is thus quite appealing for applications, no guarantees of its rate of convergence have been known. In this paper, we propose the first randomized Kaczmarz method with exponential expected rate of convergence, cf. Section 2. Furthermore, this rate depends only on the scaled condition number of A and not on the …
