Gradient Estimation with Stochastic Softmax Tricks

Witryna2. If the network has a final linear layer, how to infer the probabilities per class? Apply softmax to the output of the network to infer the probabilities per class. If the goal is to just find the relative ordering or highest probability class then just apply argsort or argmax to the output directly (since softmax maintains relative ordering). 3.
