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 … WebAbstract: Two convergence aspects of the EM algorithm are studied: (i) does the EM algorithm find a local maximum or a stationary value of the (incomplete-data) likelihood function? (ii) does the sequence of parameter estimates generated by EM converge?
