Applications both within and … WebThe EM algorithm is used for obtaining maximum likelihood estimates of parameters when some of the data is missing. More generally, however, the EM algorithm can also be applied when there is latent, i.e. unobserved, ... but that it is much easier to optimize p(X;Yj ). We rst introduce an arbitrary distribution, q(Y), over the latent variables ...
