We show that the residual f (C) in (5) can be absorbed by the first term NS i=1 optimization of C is adopted.
bility p(x ui, C) should have its model at xi, leaving the integrand p(x ui, C) ·
∂ to be trivial at x = xi. Thus, the integral Si
In the M-step the gradient of (5) w.r.t C is set to zero to maximize the conditional likelihood, and (B.3) shows that this is tantamount to setting N
