WebApr 1, 2024 · Gradient is nothing but the first derivative of the loss function w.r.t. x. This is also called the slope of the function at the point. From high-school geometry, we know that slope can have sign and depending on the sign we know which direction is “down”. WebAug 9, 2024 · REINFORCE and reparameterization trick are two of the many methods which allow us to calculate gradients of expectation of a function. However both of them make different assumptions about the underlying model and data distributions and thus differ in their usefulness.
