I listened to the lecture well (Actually, I haven't listened to it all yet). It was a difficult lecture for me, although not too difficult, but I think it was more valuable because of that. I think that learning originally shines when you gain enlightenment through difficulties, so I think that the process of listening to the lecture you uploaded was a process of gaining enlightenment for me. That's why I wanted to leave a message of gratitude for giving me this opportunity. Machine learning and deep learning felt far away, but after listening to this lecture, I feel like I've gotten a little closer. If I stop here, I'll go further away again, but thanks to the instructor's lecture, I've crossed the starting line, so I'll study until the end as much as I can and apply it to my project. Thank you for the lecture!
