We want to maximize the expected value of the log of the joint distribution of hidden states and data, $P(D,X|\Theta)$ with respect to the unknown states, conditioned on the data and the current parameters:  \begin{equation} \label{eq:Qem} \label{eqn:Qem}  \argmax_{\Theta_k} \int_X log( P(D,X|\Theta_k) ) P(X|D,\Theta_{k-1})  \end{equation}
