What is artificial intelligence? What does it look like? What can it do? Is it an omnipotent and all-powerful being? These questions, which floated around in my head like clouds, have been somewhat resolved. And I think I've even gained the ability to solve simple tasks. To understand the detailed algorithms of its internal workings, a considerable amount of knowledge in probability, statistics, and mathematics is required. So, I haven't been able to analyze or understand the algorithms themselves. However, I think I've understood that you can't do artificial intelligence without knowing even the basics. I understand why such difficult content needs to be explained in the introductory course. I think I'm now at a point where I can figure out what I need to study more deeply to do what I want to do in the future, what books I should buy, what lectures I should take on Inflearn, and what I need to think about. This is the first artificial intelligence-related course (book) I've studied, so I can't compare it to others, but I highly recommend it to anyone who is studying artificial intelligence for the first time.
