What are the best practices for reward shaping in AI?

Reward shaping involves modifying the reward signal to improve learning efficiency. Key practices include ensuring rewards are sparse, providing informative feedback, and maintaining consistency in reward structure.

Can you give an example of effective reward shaping?

What are the risks of improper reward shaping?

Improper reward shaping can lead to unintended behaviors, where the AI focuses on maximizing rewards in ways that don't align with the overall objectives, potentially causing negative outcomes.

How can I evaluate the effectiveness of my reward shaping?

You can evaluate effectiveness by monitoring the AI's performance metrics, analyzing its decision-making patterns, and ensuring it aligns with desired outcomes over time.
