Course Description:??The course style is easy to understand, real case actual cases. Carefully select the real data set as a case, through the Python Data Science library Numpy,pandas,matplot combined with the machine learning Library Scikit-learn to complete some of the column machine learning cases. The course is bas
applicable to modern programming. To use variable-size, hardware-independent data types, Java and other programming languages provide a more advanced data structure: ArrayList, Vector, and other dynamic arrays.

7 Tools for Data visualization in R, Python, and JuliaLast week, some examples of creating visualizations with Htmlwidgets and R were presented. Fortunately, there is many more options available for creating nice visualizations. Tools and libraries exist for all your favorite languages. This post plans-provide a quick reference list of some of the possible options for creating

U.S. scientists announced 11th that they first detected gravitational waves last September. This discovery confirms the prophecy of the physicist Einstein 100 years ago. Announcing the discovery was the head of the laser-interferometric gravitational Wave Observatory (LIGO).
The institution was born in the 90 's and has been observed for nearly 30 years by gravitational wave observations. So the amount of gravitational wave data that is observed shou
