WebModel code (including code for the Gumbel-softmax trick) is in models.py. Training code (including the KL divergence computation) is in train.py. To run the thing, you can just type: python train.py (You'll need to install numpy, torchvision, torch, wandb, and pillow to get things running.)

WebDec 26, 2024 · On page 5 in section "3.4 Embeddings and Softmax," it states: In our model, we share the same weight matrix between the two embedding layers and the pre-softmax linear transformation. 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 … 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.
