Straight through gumbel softmax
WebWe use Gumbel Softmax and straight-through training [8,22] to train g i. To generate the vector of Z is, we run each g i and then sample. If Z i = 0, the associated lter is not run, we simply replace the corresponding channel with a block of zeros. We use the straight-through trick: at training time during the forward pass, we use Z i and ...

WebGumbel-Softmax We still want to be able to per-form sampling, though, as it has the benefit of adding stochasticity and facilitating exploration of the parameter space. Hence, we use the Gumbel- ... Straight-Through Both relaxations lead to mix-tures of embeddings, which do not correspond to actual words. Even though this enables the Web1 Feb 2024 · The Gumbel-softmax trick is an attempt to overcome the inability to apply the re-parameterization trick to discrete data. It is the result of two insights: 1) a nice parameterization for a discrete (or categorical) distribution is given in terms of the Gumbel distribution (the Gumbel trick); and 2) although the corresponding function is non ...
