Instead, it focuses on the key mathematical concepts that you’ll encounter in studies of machine learning. We’ll start with some basic algebra to get started with equations and functions, then we’ll dive into some differential calculus to explore derivatives and optimisation. We’ll also look...
is a function taking parameter x and returning whether x is or isn’t a part of the set. We’ll look at functions in a later blog post. To indicate how many elements are in any given (finite) collection we can use notation . So and (where E is the English alphabet). Of course t...

Well, most languages let you work with exactly these functions! For example, take a look at this SQL expression. (SELECT 1 UNION SELECT 2 UNION SELECT 3) INTERSECT (SELECT 3 UNION SELECT 4) What will that return? It returns only 3 because 3 is an element of both collections. This exam...
