    Definition

    Reinforcement learning improves action strategies based on rewards.

    A learning paradigm in which an agent learns a strategy to maximize expected cumulative reward through interaction.

    Simply explained

    An agent acts, experiences consequences, and learns which steps pay off in the long term.

    Why it matters in practice

    The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.

    Example from business

    A system learns an inventory strategy from simulated states, actions, and costs.

    Limits and pitfalls

    • Poorly specifying rewards, confusing simulation and reality, or allowing exploration in risky environments without checks.

    Origin & history

    RL combines dynamic programming, control theory, and machine learning and was formalized in the 20th century.

    Use in mid-sized companies

    • Possible example: A system learns an inventory strategy from simulated states, actions, and costs.

    Frequently asked questions

    What does reinforcement learning mean?

    A learning paradigm in which an agent learns a strategy to maximize expected cumulative reward through interaction. What mistakes should be avoided? Poorly specifying rewards, confusing simulation and reality, or allowing exploration in risky environments without checks.
