Frequently asked questions

What is the difference between supervised learning and reinforcement learning?

Supervised learning learns from labeled examples (input-output pairs), while reinforcement learning learns from interactions with an environment, receiving rewards/penalties for actions. Supervised learning requires a dataset.

Can off-policy methods be less stable, especially when using function approximation?

Off-policy methods can be less stable, especially with function approximation. The choice between different approaches depends on whether you prioritize sample efficiency or stability.

What are the key challenges in reinforcement learning?

Reinforcement learning faces challenges such as reward shaping, exploration-exploitation dilemmas, and ensuring convergence to optimal policies. These issues require careful design and tuning of algorithms.
