WebJul 16, 2024 · In this post you learned what the Gumbel-softmax trick is. Using this trick, you can sample from a discrete distribution and let the gradients propagate to the weights that affect the distribution's parameters. This trick opens doors to many interesting applications. WebNov 3, 2016 · We show that our Gumbel-Softmax estimator outperforms state-of-the-art gradient estimators on structured output prediction and unsupervised generative modeling tasks with categorical latent variables, and enables large speedups on semi-supervised classification.
