Luy Gumbel-Softmax ak Reparametraasioŋ?

Why is a categorical sample difficult to train through with ordinary backpropagation?
The guide explains gradients do not pass through a hard discrete jump.
What does the reparameterization trick aim to do?
The guide describes moving randomness into a noise source and preserving a smooth path.
How does Gumbel-Softmax approximate a categorical choice?
The guide gives the noisy softmax construction for differentiable categorical sampling.
What happens to the distribution as temperature becomes large?
High temperature yields a smoother distribution over categories.
What happens as temperature approaches zero?
The guide says low temperature sharpens toward a near one-hot vector.
