This is a lecture that I found like a ray of light when I was frustrated while studying text mining on my own :-) Why is it so easy to understand when it explains all the hot methodologies that are often covered in theses these days..!! (Honestly, if I were to take it at school, it would be a 1-semester lecture..How come you explain it so compactly?>.<) More than anything, it was a practical lecture, not a theory lecture, so it was very helpful in practice, and it was a lecture that completely condensed knowledge, so I didn't regret the tuition at all. In fact, it felt cheap..ㅠㅠ One more thing that is the most...perfect thing about this lecture..!! When I leave a question, the teacher gives feedback almost in real time, and tries to solve it together until the end, so I dare to give a thumbs up!!^^bb Thank you, teacher~~
