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 ... Web8 Nov 2016 · Whereas DARN, MuProp, NVIL, Straight-Through Gumbel-Softmax present a way to train the same forward model, Discrete VAE optimizes a new objective altogether. It's an open question what the "right forward pass" is, but it makes it hard to compare Discrete VAE with other work since they have different forward passes and optimization strategies. distance from lavergne to smithville tn
