![]() Whilst the score function only requires the value Pathwise derivative estimator is commonly seen in the reparameterization trick Seen as the basis for policy gradient methods in reinforcement learning, and the These are the score function estimator/likelihood ratioĮstimator/REINFORCE and the pathwise derivative estimator. There are two main methods for creating surrogate functions that can beīackpropagated through. It is not possible to directly backpropagate through random samples. Generally follows the design of the TensorFlow Distributions package. Graphs and stochastic gradient estimators for optimization. This allows the construction of stochastic computation ![]() ![]() The distributions package contains parameterizable probability distributionsĪnd sampling functions.
