R VS Python in Data science: The winner is ...In the "Best" data Science tools game, R and Python have their own pros and cons. The choice between the two depends on the use of the background, the need to learn spending and other tools that are often usedMartijn Theuwissen published in Datacamp.At Datacamp, students often ask us about their daily data analysis tasks using R or Python. Although we mainly offer interactive R tutorials, we always answer

-Newton method, and compared with the gradient descent algorithm, the advantages of these algorithms are:
First, there is no need for manual selection of step size; second, it is usually faster than gradient descent algorithm;
But the downside is more complicated.
multi-Class classification problem
For multiple classification problems, it can be seen into two categories of classification problems: keep One of them, the rest as the other class.
For each Class I trains a classifier of a logistic

This is a two-day short-term training course (two full days, of course), probably seven videos, each of which is followed by a programming assignment that can be completed within one hours of each job. This is my second class to learn Python (the first one is Codecademy python, very early to see, a lot of content are not remembered), then watch video + programming One hours a day, six days to finish, the effect is good, with Python write basic p

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.

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
