I/O ar problem on C time r learning
Remember long ago, when looking for a question about Vim matching brackets, I saw a saying that parentheses are not regular. At that time, I did not go into details, but I just wrote down this statement. Recently, Coursera opened a course on automation and listened to it. It also said that parentheses are not regular and no proof is provided. This leads to my curiosity.

Mooc of learning? The majority of the courses completed are less than the single-digit percentage of the number of elective classes. Coursera Data Science certificate sold a hundred thousand of (with the impression that the data might be wrong), and finally finished capstone project with just over 500 people. Moreover, most of those who have finished have a computer science background, and the 0 base is rare.
This is still the result of teaching Pyt
Ng's machine learning courses on Coursera are the best choice for getting started. In addition, Yaser Abu-mostafa's machine learning program is more focused on theory, but also suitable for beginners. Learning deep learning does not require mastering machine learning, but it can be helpful if you have some understanding. In addition, Learning Classic machine learning, not just deep learning, can give us a deep theoretical background ———— because deep
