When I started learning Machine Learning (ML) two years back, I had many questions around which algorithms to use, how to correlate it to datasets, etc. The answer depended on many factors like the size of data, expected output, and available computational resources. I was then introduced to the ML cheat sheets which acquainted me with the frequently used algorithms, packages, and functions.

This post contains the top three cheat sheets that I would recommend to a beginner who is interested in identifying and applying ML algorithms to different problems. Given how rapidly this domain is evolving, the trending algorithms are progressing too. Therefore, it is important to understand the algorithms that help fit the areas of supervised and unsupervised learning, classification and regression, and so on.

Python and Scikit Cheat sheets

Most developers work in Python or R language for implementing the ML algorithms. I work in Python, and so the following two cheat sheets have been very useful to me.

The Python cheat sheet was prepared by DataCamp, and can be used as a quick reference to guide through ML Python packages and data structures as well.

Scikit-learn is an open-source Python library that implements a wide variety of ML, preprocessing of data, and cross validation as well as visualization of algorithms. This library belongs to the must know for every aspiring data scientist, so I highly recommend this cheat sheet.
