Reinforcement Learning (RL), a key subdivision of the broader machine learning domain, involves creating agent programs that progressively refine their actions within an environment to diminish a loss function, thereby enhancing performance. This innovative approach has been deployed across an array of sectors, including robotics, finance, healthcare, and gaming, triggering substantial advancements over recent years. Researchers continue to devise innovative algorithms and architectures to grapple with intricate challenges inherent in these fields.
