Tensorflow batch size meaning
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.

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.
