The AI lecture utilizing Databricks seems unique, and I thank you for the excellent lecture. However, it would have been better if you had provided more overview explanations for each detailed unit. For example, it would have been even better if you had explained the functions of each menu in machine learning and supplemented how each code is utilized in which menu. Additionally, for those taking this lecture, Spark or Databricks is more of a focus, so there are likely many people who are interested in AI but lack knowledge. If you had supplemented this point as well, it would have been an even more excellent lecture.
