I was totally confused by a seemling simple first derivative
Given the Kullback-Leibler divergence function between
a true pdf function P(x,theta) and an approximation pdf
where theta=[theta1,theta2, ..., thetan]'.
= \integration Q(theta)*log(P(x,theta)/Q(theta)) dtheta
So how to derive the first derivative of KL with respect
Thanks for your helpful advices.
