Gumbel softmax loss

WebChannel selection using Gumbel Softmax 5 In addition, the loss that AIG uses cannot be adapted to network pruning, since it does not allow any the activation rate of any gate to … WebApr 6, 2013 · It turns out that the following trick is equivalent to the softmax-discrete procedure: add Gumbel noise to each and then take the argmax. That is, add independent noise to each one and then do a max. This doesn’t change the asymptotic complexity of the algorithm, but opens the door to some interesting implementation possibilities.
