Question: What is the difference between \'on-policy\' and \'off-policy\' learning?

Options:

2. On-policy uses supervised learning, off-policy uses unsupervised learning
3. On-policy is faster than off-policy
4. There is no difference

Correct Answer: On-policy learns from the current policy, off-policy learns from a different policy
