Overall, it's good content. Java machine learning is an unfamiliar field, but there are almost no lectures introducing it, so it was very helpful. However, since I mostly use Java for web, it's a bit difficult.
Just as Java played a pivotal role in transitioning from web (jsp) to mobile (android), it is expected that Java will play a major role in data analysis (weka). Thank you for your good review.
I was very satisfied with the feedback on quick questions and the supplementary content for the missing content. The lecture content was also explained well so that even beginners could easily understand it, which was very helpful. Thank you.
