The Gumbel-max trick is a method to draw a sample from a categorical distribution, given by its unnormalized (log-)probabilities. Over the past years, ... |
The well-known Gumbel-Max trick for sampling from a categorical distribution can be extended to sample k elements without replacement. We show how to implicitly ... |
Structured variables include matching, graphs, subsets, etc. Recent structured variables extend the Gumbel-Softmax trick. • Define perturbed sampling algorithm. |
