Summary: What is data mining. What is machine learning. And how to do python data preprocessing. This article will lead us to understand data mining and machine learning technology, through the Taobao commodity case

knowledge to show Ah, the data ah what the work, MATLAB is difficult to complete. As a mature programming language with a rich and comprehensive library of classes, Python is indeed more capable of ' in-depth ' learning requirements. I think the biggest problem of MATLAB is: As a language, it is not expressive enough . MATLAB without pointers and references is a

The python language has been increasingly liked and used by program stakeholders in recent years, as it is not only easy to learn and master, but also has a wealth of third-party libraries and appropriate management tools; from the command line script to the GUI program, from B/S to C, from graphic technology to scientific computing, Software development to automated testing, from cloud computing to virtualization, all these areas have

graphs, but the results can be further processed to obtain more detailed results. Each data also has an agent value, that is, the browser's user_agent information, through this information to know the operating system used,so the statistical results generated in the previous step can also be differentiated by operating system differences. Agent value: v. To distinguish a bar chart from an operating system (windows/non-Windows) Not all

functions of read_csv and read_table are as follows:Read a text file by blockWhen working with very large files, or finding the set of parameters in a large file for subsequent processing, you only need to read a small part of the file or iterate over the file by block.Reading a few lines requires setting the nrows parameter, where the nrows subscript is starting from 0. So nrows=2 represents the first 3 lines. in [+]: result=pd.read_csv ('/home/zhf/1.csv ', nrows=2)in [+]: ResultOUT[20]:1 2 3

. This array can be seen as a simulation of the daily observations of 4 random variables in a year. Here we use the Python standard namedtemporaryfile to store the data, and these temporary files are then automatically deleted.The following will save the array in a CSV file and check its size with the following code:tmpf=namedtemporaryfile () np.savetxt (tmpf,a,delimiter=',') print ( " Size CSV File ", GetS
