Machine Learning and Data Science Cheat Sheet

You can download the new machine learning cheat sheet here (PDF format, 14 pages.)

Originally published in 2014 and viewed more than 200,000 times, this is the oldest data science cheat sheet - the mother of all the numerous cheat sheets that are so popular nowadays. I decided to update it in June 2019. While the first half, dealing with installing components on your laptop and learning UNIX, regular expressions, and file management hasn't changed much, the second half, dealing with machine learning, was rewritten entirely from scratch. It is amazing how things have changed in just five years!

Written for people who have never seen a computer in their life, it starts with the very beginning: buying a laptop! You can skip the first half and jump to sections 5 and 6 if you are already familiar with UNIX. This new cheat sheet will be included in my upcoming book Machine Learning: Foundations, Toolbox, and Recipes to be published in September 2019, and available (for free) to Data Science Central members exclusively. This cheat sheet is 14 pages long.

Comment by Ravi Polavarapu on June 7, 2019 at 12:19pm: Thank you. This is excellent information.

Comment by Vincent Granville on June 6, 2019 at 8:29pm: The cheat sheet, after over 5 years, has been entirely re-written and is now available as a PDF document from this article. Broken links have been removed and replaced by new ones, but that is just a very tiny part of the complete re-vamping that I worked on over the last few days.

Comment by Dr S Kotrappa on June 30, 2016 at 3:12pm: Thank you so much Dr Vincent Granville for so much stuff on Data Science education and career, its really so much useful and helpful for all aspirants of Data Scientist. Now I am more particular of Data Science Education & Research startup along with Computer Science & Software Engineering because of my background, experience and education (domain). Please some one can help and suggest some ideas me , How I can go about Data Science Education , Training & Research Startup (work from home) along with Computer Science & Software Engineering . Thanks Dr S Kotrappa
