WebAug 14, 2024 · No, PyTorch does not automatically apply softmax, and you can at any point apply torch.nn.Softmax() as you want. But, softmax has some issues with numerical … WebMay 20, 2024 · There is one such distribution — the GumbelSoftmax distribution. PyTorch does not have this built-in, so I simply extend it from a close cousin which has the right rsample () and add a correct log prob calculation method.
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 ...

I've currently implemented my model to use just one embedding layer for both source and target tensors, but I'm wondering if there would be a way that I could use the weights of the embedding layer as a linear layer.
