| • | There are several
different ways to show that |
|||||||
| EM converges. |
||||||||
| • | My favorite
method is to show that there is a |
|||||||
| cost function
that is reduced by both the E-step |
||||||||
| and the M-step. |
||||||||
| • | But the cost
function is considerably more |
|||||||
| complicated than
the one for K-Means. |
