Weprovideargumentsfortreating the learned non-convergent short-run MCMC as a valid model. We show thatthe learned short-run MCMC is capable of generating realistic images.
After training, we learn the dynamicsx = Mθ(z),whereMθ consists18 of K-steps of gradient descent dynamics (the noise term of the Langevin dynamics is negligible compared to the19 gradient termafterlearning).
