Inverse Reinforcement Learning

ɪnˈvɜrs rɪˈnɪfɔrsmənt ˈlɜrnɪŋ

Inverse Reinforcement Learning (IRL) is a type of machine learning where the goal is to infer the underlying reward function that an agent is optimizing, based on its observed behavior. Unlike traditional reinforcement learning, which requires a predefined reward structure, IRL seeks to understand the motivations behind an agent's actions in a given environment. This approach is particularly useful in scenarios where the reward function is difficult to specify but the expert behavior is available for observation. Common use cases include robotics, autonomous driving, and human behavior modeling, where learning from expert demonstrations can lead to more effective and human-like decision-making processes.
