Action Chunking

A policy output method in robot learning in which a policy network's single forward pass predicts a sequence of actions for several future steps, known as a chunk, rather than only the action for a single timestep. The robot executes the sequence in order before replanning, reducing the computation and jitter of high-frequency replanning.
