The Gumbel-Max Trick was introduced a couple years prior to the Gumbel-softmax distribution, also by DeepMind researchers [6]. The value of the Gumbel-Max Trick is that it allows for sampling from a categorical distribution during the forward pass through a neural network [1-4, 6]. Let’s see how it works by following ...

WebWhen τ = 0, the softmax becomes a step function and hence does not have any gradients. The straight-through estimator is a biased estimator which creates gradients through a proxy function in the backward pass for step functions. This trick can also be applied to the Gumbel Softmax estimator: in the equations above, z (using argmax) was the ... WebSep 9, 2024 · I am using softmax at the end of my model.
