>Hi, all

>Why is the E step of LDA iterative? I mean the updating formula of \gamma
>and \phi.
Because there is interdependency between themselves

>In my algorithm, there are more variables to be updated in E step,

>is there any situation that such iterative E step does not converge or
>oscillate repeatedly?
