Online Encyclopedia on Data Science using Python and Jython
Contributors (names will be filled later). Editor S.Chekanov

The goal of this project is to create a free online encyclopedia on data science. Each theoretical principle and the description of numeric algorithm will be supported by a programming code implemented using Python (+ external C/C++ libraries) or Jython (+ external Java libraries).

Everyone is welcome to contribute to this wiki. One can login or request account using the top-right menu. Read the section How to edit wiki text. Please use your real name and email during the registration since this will help generate the author list (all people contributed to this book will be included to the author list).

Here are some tips:

• Use Python or Jython code for real-world examples to illustrate theoretical principles;
• Do not use complex templates which cannot easily be converted to LaTeX using top-right action menu. Always use imported BibTeX files for citations;
• Your wiki text can link 2,243,932 wiki articles that already exist in HandWiki. One can upload images, or reference the exiting images from Wikipedia Commons or DataMelt projects.
• If you see a red box on top of this page, then access to some examples and Java class documentation is till restricted. Read read this section.
