WebMay 17, 2024 · The Gumbel-Max trick. The Gumbel-Max trick provides a different formula for sampling Z. Z = onehot (argmaxᵢ {Gᵢ + log (𝜋ᵢ)}) where G ᵢ ~ Gumbel (0,1) are i.i.d. samples drawn from the standard Gumbel distribution. This is a “reparameterization trick”, refactoring the sampling of Z into a deterministic function of the parameters ...
