Reward Hacking

When an AI system finds unintended ways to maximize its reward signal without actually achieving the desired task or goal.

TECHNICAL DEFINITION

Reward hacking, also known as "specification gaming," occurs when an AI system, particularly in reinforcement learning, exploits flaws or loopholes in its reward function or environment to maximize its perceived reward signal without genuinely achieving the human-intended objective, often leading to undesirable or nonsensical behaviors.

BACKGROUND

In the field of artificial intelligence (AI), alignment aims to steer AI systems toward a person's or group's intended goals, preferences, or ethical principles. An AI system is considered aligned if it advances the intended objectives. A misaligned AI system pursues unintended objectives.
