Did you know?
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. feb 1995 · this paper we provide sufficient conditions for convergence of a general class of alternating estimationmaximization (EM) type continuous-parameter estimation algorithms with respect to a...
