Machine Learning Cheat Sheet (pdf)
If you need to memorize machine learning formulas for an exam, this might be the very thing.
On the other hand, if you are sitting at your console, you are likely to have online or hard copy references with this formula and more detailed information.
A generally helpful machine learning cheatsheet would some common cases where each algorithm has been successful. Perhaps even some edge cases you are unlikely to think about.
The algorithms are rarely in question. Proper application, well, that’s an entirely different story.
