Three ways to view memory usage (i.e. “disk usage”) on your Mac, in descending order of preference.

For the below examples, assume we have a binary classification task where the class label is $y \in {0, 1}$, and the model’s predictions are $\hat{y} \in {0, 1}$

A brief cheat sheet / reference guide containing the definitions, formulas, and explanations of the most commonly used model evaluation metrics for binary classification tasks.

The definition of “tidy data” is simple:

I’ve always been intimidated by vim. After taking MIT’s Missing Semester Course (a free online course that I’d highly recommend), I learned about a built-in utility called vimtutor that automatically comes installed with vim.
