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 … WebSteps in EM Algorithm The EM algorithm is completed mainly in 4 steps, which include I nitialization Step, Expectation Step, Maximization Step, and convergence Step. These steps are explained as follows: 1st Step: The very …
