On the convergence of the em algorithm
Web1 de dez. de 2006 · As shown in Table 2 and Fig. 1, the EM algorithm increases linearly with the number of iterations as the data set changes from (a) to (e), while there is little variation in the number of iterations for the ε-accelerated EM algorithm and its convergence is significantly faster.For example, for δ = 10-6 and the data set (d), the ε … 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 …
