we have a cost function for the generator network which is an expectation of X sampled from the generator and then applying f of X and we want to figure out what f of X should be to make this cost function give us a maximum likelihood as a hint you should first start by showing the following that the derivatives with respect to the parameters of the cost function are given by this expectation of f of X multiplied by the derivatives of the likelihood and if you'd like you could actually just take that as a given and
