WebFirst, the Gumbel-Max Trick uses the approach from the Reparameterization Trick to separate out the deterministic and stochastic parts of the sampling process [1-4,6]. We do this by computing the log probabilities of all the classes in the distribution (deterministic) and adding them to some noise (stochastic) [1-4,6].
