Webthe convergence of EM sequence as proved in their Theorems 2 and 3 is cast in doubt. Other results on the monotonicity of likelihood sequence and the convergence rate of EM sequence (Theorems 1 and 4 of DLR) remain valid. Despite its slow numerical convergence, the EM algorithm has become a very popular computational method in …
WebThe EM algorithm is a popular iterative method for finding the maximum likelihood estimate when the likelihood function is either non-analytical or its functional form is too difficult to maximize directly. In this paper we analyze the convergence properties of the EM algorithm. By representing the E step in a Taylor series with remainder we obtain a … WebAn example is given showing that a sequence generated by a GEM algorthm need not converge under the conditions stated in Dempster et al., (1977). Two general convergence results are presented which suggest that in practice a GEM sequence will converge to a compact connected set of local maxima of the likelihood function; this limit set may or …
Web10 de nov. de 2013 · The Expectation-Maximization (EM) algorithm is widely used also in industry for parameter estimation within a Maximum Likelihood (ML) framework in case of missing data. It is well-known that EM shows good convergence in several cases of practical interest.
