Reinforcement Learning

Definition of Reinforcement Learning

Reinforcement learning is a subfield of machine learning that focuses on training an agent to make decisions in an environment to maximize a cumulative reward. Unlike supervised and unsupervised learning, reinforcement learning does not rely on labeled data or predefined patterns.

Through this iterative process, the agent gradually improves its decision-making abilities and develops a strategy to achieve the highest possible reward. Reinforcement learning has been successfully applied in various domains, including robotics, game playing, and autonomous systems.

Components of Reinforcement Learning

Reinforcement learning is a subfield of machine learning that focuses on training agents to make decisions based on trial and error. It consists of three main components: the agent, the environment, and the rewards. The agent is the entity that takes actions in the environment, while the environment is the external world in which the agent operates. The rewards serve as feedback for the agent’s actions, guiding it towards learning optimal strategies. By interacting with the environment and receiving rewards, the agent learns to maximize its cumulative reward over time. This iterative process of learning through trial and error makes reinforcement learning a powerful technique for training AI applications.
