## How is reinforcement learning used in control optimization?

Reinforcement Learning (RL) is a technique useful in solving control optimization problems. By control optimization, we mean the problem of recognizing the best action in every state visited by the system so as to optimize some objective function, e.g., the average reward per unit time and the total discounted reward over a given time horizon.

## How are reinforcement learning algorithms different from model free algorithms?

Model-Free: In contrast, in a model-free algorithm, the agent uses experience to learn the policy or value function directly without using a model of the environment. Here, the agent only knows about the possible states and actions in an environment and nothing about the state transition and reward probability functions.

## When does prediction error decrease in reinforcement learning?

Initially the target and prediction networks are uncorrelated, and the prediction error will tend to be high. However, during the learning process this error will decrease for states the agent visited frequently, just like in the dynamics prediction method we discussed before.

## How is reinforcement learning used in deep learning?

Reinforcement Learning is a part of the deep learning method that helps you to maximize some portion of the cumulative reward. This neural network learning method helps you to learn how to attain a complex objective or maximize a specific dimension over many steps.

## What should you know about reinforcement learning algorithms?

You need to remember that Reinforcement Learning is computing-heavy and time-consuming. in particular when the action space is large. Parameters may affect the speed of learning. Realistic environments can have partial observability. Too much Reinforcement may lead to an overload of states which can diminish the results.

## Is there a reinforcement learning traffic light controller?

In the paper “Reinforcement learning-based multi-agent system for network traffic signal control” [3], researchers tried to design a traffic light controller to solve the congestion problem.
