Web to understand em more deeply, we show in section 5 that em is iteratively maximizing a tight lower bound to the true likelihood surface. In this tutorial paper, the basic principles of the algorithm are described in an informal fashion and illustrated on a notional example. It does this by first estimating the values for the latent variables, then.
