Reinforcement Learning

Reinforcement learning is a type of machine learning, in which an agent explores an environment to


learn how to perform desired tasks by taking actions with good outcomes and avoiding actions with
bad outcomes.

A reinforcement learning model will learn from its experience and over time will be able to identify
which action leads to the best rewards.

In reinforcement learning, an agent interacts with an environment with an objective to maximize its
total award.

The agent takes an action based on the environment state and the environment returns the reward
and next state. The agent learns from trial and error, initially taken random action and over time
identifying the actions that lead to long-term rewards.

Every reinforcement learning system consists of these four main components:

 An agent
 An interactive environment
 An algorithm that steers the action taken by the agent
 A feedback mechanism to reward/penalize the agent as per the action
