Reinforcement Learning
Reinforcement Learning (RL) is a machine learning paradigm where an agent learns to make decisions by interacting with an environment to maximize cumulative rewards. It involves trial-and-error learning through actions, feedback in the form of rewards or penalties, and the development of policies to achieve long-term goals. RL is widely used in areas like robotics, game playing, autonomous systems, and recommendation engines.
Developers should learn reinforcement learning when building systems that require autonomous decision-making in dynamic or uncertain environments, such as robotics, self-driving cars, or game AI. It is particularly useful for problems where explicit supervision is unavailable, and the agent must learn from experience, making it essential for applications in control systems, resource management, and personalized user interactions.
