In a reinforcement learning scenario, the environment models the dynamics with which the agent interacts. The environment:
Receives actions from the agent
Outputs observations resulting from the dynamic behavior of the environment model
Generates a reward measuring how well the action contributes to achieving the task
You can create predefined and custom environments in MATLAB. For more information, see Create MATLAB Reinforcement Learning Environments.
