Abstract
We propose a general and scalable approximate
sampling strategy for probabilistic models with
discrete variables. Our approach uses gradients
of the likelihood function with respect to its dis-
crete inputs to propose updates in a Metropolis-
Hastings sampler. We show empirically that this
