Which of the following is an example of a closed-loop control system?

• Opening a window to cool down a room.

• Turning on a fan manually.

• A thermostat maintaining room temperature.

• Leaving the heater on when leaving the house.

What are the four components of a Markov decision process?

• Data, algorithms, models, results

• Goals, rewards, penalties, actions

• Inputs, outputs, feedback, control

• States, actions, transition function, reward function

What is the main goal of policy optimization in reinforcement learning?

• To minimize the number of actions taken

• To simplify the decision-making process

• To maximize the reward
