Implementing the Apriori Data Mining Algorithm with JavaScript

I’ve been working on my thesis for a little too long. I’m hopefully about finished, but that is beside the point. Part of what I’ve been working on revolves around the Apriori Data Mining algorithm. If you know what Apriori is, and you are looking for how to implement it, then this post is for you.

I’ve created a JavaScript implementation of Apriori. Admittedly, JavaScript isn’t probably the most efficient programming language to implement Apriori with; however, I was constrained to use it for my project [1]. There have been many improvements to the Apriori Algorithm since Agrawal suggested it in 1993. I chose to instead create a simple implementation of the original algorithm. First, learn how the algorithm works; second, learn how to optimize it.
