Reinforcement Learning Tutorial

Welcome to the Reinforcement Learning Tutorial! This guide will provide you with an introduction to the fundamental concepts of reinforcement learning and how it works.

What is Reinforcement Learning?

Reinforcement learning is a type of machine learning where an agent learns to make decisions by performing actions in an environment to achieve a goal. The agent receives rewards or penalties based on the outcomes of its actions.

Key Components of Reinforcement Learning

Agent: The decision-maker that selects actions.
Environment: The surroundings in which the agent operates.
State: The current situation of the agent in the environment.
Action: A decision made by the agent.
Reward: A scalar value that indicates how good or bad the action was.

Examples of Reinforcement Learning

Playing a video game
Operating a robot
Managing a portfolio

How Does It Work?

Initialize the agent and environment.
Choose an action based on the current state.
Perform the action and observe the outcome.
Update the agent's policy based on the reward received.
Repeat steps 2-4 until the goal is achieved.

Common Algorithms
