Web16 Feb 2024 · Introduction. Reinforcement learning algorithms use replay buffers to store trajectories of experience when executing a policy in an environment. During training, replay buffers are queried for a subset of the trajectories (either a sequential subset or a sample) to "replay" the agent's experience. In this colab, we explore two types of replay ...

WebFigure 1. Typical batch norm in Tensorflow Keras. The following script shows an example to mimic one training step of a single batch norm layer. Tensorflow Keras API allows us to peek the moving mean/variance but not the batch mean/variance. For illustrative purposes, I inserted codes to the Keras python APIs to print out the batch mean/variance.
