How do I choose the right reward function for my AI model?

Choosing a reward function depends on your specific goals. What task is your AI model designed to perform?

It's for a reinforcement learning task in a game environment.

In that case, consider reward functions that encourage desired behaviors, like winning the game or completing levels.

Should I use sparse or dense rewards?

Sparse rewards can be challenging but may lead to more generalizable strategies, while dense rewards provide more immediate feedback.

What are some common pitfalls to avoid?

Common pitfalls include reward hacking, where the AI finds unintended ways to maximize rewards, and misalignment with human values.
