useful and interesting tool for connecting to the thought matrix. One of the benefits of college expertise is here, and it's easy to get a clear picture of what expertise needs to be applied in the relevant fields, even if it's not good at the time. This is also I think that the need to go to graduate school, the necessity of continuing to enter a higher field, you know that your horizons and more in-depth knowledge can be researched and applied.https://class.coursera.org/Duke University: Image

Recently, I have been learning the course Web Intelligence and big data on Coursera. Last Friday, an Indian teacher assigned a homework assignment asking me to write a mapreduce program and use python for implementation. The detailed description is as follows: Programming assignment for hw3 Homework 3 (programming assignment) Download data files bundled as A.

Find a good article on the internet, paste it directly, add some supplements and your own understanding, and count as this article. My education in the fundamentals of machine learning has mainly come from Andrew Ng's excellent Coursera course on the topic. one thing that wasn't covered in that course, though, was the topic of "Boosting" which I 've come into SS in a number of different contexts now. fortunately, it's a relatively straightforward topi

And then the matrix operation and computing function is not very good.Later, with his interest in data science and machine learning, there were some Python-based courses on the edx, Coursera, Udacity and other platforms. One of the most rewarding lessons for the utility is EdX's two Python courses (6.00.1x and 6.00.2X
