What are reward shaping techniques in AI?

Reward shaping techniques are methods used to modify the reward signal in reinforcement learning to improve learning efficiency.

Can you give me an example of how reward shaping works?

Sure! For instance, in a maze-solving task, instead of only rewarding the agent for reaching the goal, you can give small rewards for moving closer to the goal.

What are the benefits of using reward shaping?

The benefits include faster convergence, improved exploration, and the ability to guide the agent's learning process more effectively.

Are there any risks associated with reward shaping?

Yes, if not done carefully, it can lead to unintended behaviors or suboptimal policies, as the agent may exploit the shaped rewards.
