The Concrete Distribution: A Continuous Relaxation of Discrete Random Variables
ICLR, Volume abs/1611.00712, 2017.
The reparameterization trick enables optimizing large scale stochastic computation graphs via gradient descent. The essence of the trick is to refactor each stochastic node into a differentiable function of its parameters and a random variable with fixed distribution. After refactoring, the gradients of the loss propagated by the chain ru...More
