MBRL — Model-Based Reinforcement Learning

Fact

A reinforcement learning method using a learned world model to choose actions.

In Plain Words

MBRL is like trying a skateboard trick in a video game first. Your knees send a thank-you card.

It learns a mini world, then tries choices there before acting. Robots and self-driving cars use it to cut real test runs, but a bad model can steer them wrong.
