Reinforcement Learning

Definition

Reinforcement learning is a type of machine learning where an agent learns to make decisions by taking actions in an environment to maximize cumulative rewards over time. It focuses on how agents should take actions in a given situation to achieve the best possible outcomes, making it essential for optimizing complex systems, such as those found in energy management and grid operations.
