Hello, Beopgyeong. Thank you for your great review. Unlike other technologies, reinforcement learning has a high barrier to entry. However, if you follow this lecture slowly, you will be able to understand it sufficiently even if it takes some time. Reinforcement learning is a powerful technology that can be used in various fields such as improving work productivity and investment analysis, so the time spent studying is well worth it. Beopgyeong, even if it is a bit difficult at first, I hope you don't give up and take the course to the end. Thank you.
