I finished the linear algebra lecture, and since Inflearn was on sale, I bought it right away. I haven't taken many lectures yet, but since the beginning of the lecture covers all the contents, I checked the contents and it really has everything I wanted. The only regret is that since I'm studying artificial intelligence, I should have focused more on Bayesian statistics? However, I know very well that it's not easy to cover both mathematical statistics and Bayesian statistics in one lecture. Therefore, if there's an opportunity, I think it would be great if Bayesian statistics were added later. I'm so satisfied with each lecture, so I bought one each of Introductory Vector Calculus, Differentiation, and Integration because they were on sale. Thank you for the great lecture.
