the energy function and the D generator just tries to produce data that is compatible with that energy function so I hope that concept of what an energy function is is a bit clearer and in any again any machine learning problem can be formulated in terms of an energy function now what is not done so far is what we alluded to a little bit before in the classifier example and also here so right now when we want to Train again we simply take the generator to whose data now what's the generator skull the generators goal is to hit
