Straight through gumbel softmax

Web• The Taylor estimator outperforms Gumbel-Softmax, REINFORCE and Straight-Through baselines on FED. • We argue that the inferior performance of Gumbel-Softmax is the consequence of biased and spiky distribution explained in Section 2 and the unusually high perplexity on real data, even with temperature annealing during the training phase [18]. Web15 Jun 2024 · The Gumbel-Max trick is the basis of many relaxed gradient estimators.These estimators are easy to implement and low variance, but the goal of scaling them comprehensively to large combinatorial distributions is still outstanding.Working within the perturbation model framework, we introduce stochastic softmax tricks, which generalize …

Web1 Answer. Passing directly the output of the softmax is also common (among the few textual GANs out there), e.g. see the improved Wasserstein GANs (WGAN-GP). With hard Gumbel-softmax (+ straight-through estimator), you pass one-hot encoded vectors, which is the same as what you have with real data. If you pass the output of the softmax, the ...
