the negative phase in the Boltzmann machine that trying to train the discriminator in the inner loop you just couldn't get it to keep up with the generator and the outer loop and that would prevent it from converging to anything useful yeah I share that intuition yeah what turns out to not be the case a lot of the time with machine learning algorithms it's really hard to predict ahead of time how well they'll actually perform you have to just run the experiment and see what happens and I would say I still today don't have
