Penalized maximum-likelihood image reconstruction using space …

WebThis paper describes the space-alternating generalized EM (SAGE) method, which updates the parameters sequentially by alternating between several small hidden-data spaces defined by the algorithm designer. We prove that the sequence of estimates monotonically increases the penalized-likelihood objective, we derive asymptotic convergence rates ... Webconvergence. In order to speed up the convergence of the EM algorithm, [6] proposes the space-alternating generalized EM (SAGE) algorithm. [7] and [8] show that the SAGE algorithm does yield faster convergence in terms of DOA estimation. The EM and SAGE algorithms in ML direction finding are usually derived under known noise [4], [5], [7], [8 ... device hardware build related constants

DOA Estimation using fast EM and SAGE Algorithms

WebIn case of EM, each EM iteration consists of an E(Expectation)-step and an M(Maximization)-step for all M sources a shown in Alg. 1. An alternative of EM called SAGE (Space Alternating Generalized EM) [14] was proposed in [8] for the purpose of AoA estimation. Instead of carrying out E and M steps for all the sources together, SAGE updates Web1. nov 1994 · Space-Alternating Generalized Expectation-Maximization Algorithm IEEE Xplore Authors: J.A.
