WebAug 29, 2024 · Being close to one-hot seems like it comes from the temperature parameter, which can be set low or high for both Gumbel-Softmax and regular softmax. Gumbel-Softmax with high temperature could give you samples close to [0.5, 0.5]. Softmax with low temperature would give you samples close to [1, 0]. – Grady S Apr 11, 2024 at 17:34 WebDec 6, 2024 · When fowarding, the code use an argmax to get an actual one-hot vector.
