There are thousands of packages and hundreds of functional formulas in the field of data science, although you don't need to know all of this, but it's important to have a quick look at your study. Learning Big Data includes understanding of statistics, math, programming knowledge (especially R, Python, SQL), and understanding the business to drive decisions. The
Many big companies claim to be building the data Science department, how the department should be formed, and everyone is touching rocks across the river.

I often heard the chief executive say, "If you want to submit a job, data must be good !!』 I believe this sentence involves many people, but is it true?
I have been programming for so many years, although I still like data, but I have never used any data in the old saying, I have always been skeptical about the long term.
Today, I am going to hear about the s
Python has become increasingly popular among data science enthusiasts, and it is important that it brings a complete system to the universal programming language. With Python you can not only transform operational data, but also create powerful piping commands and machine learning processes in a single system.
