k-means clustering
k-means clustering is a neat way to find ‘centers of density’ in a group of points. It’s useful for applications like finding natural groups, simplifying visualizations, and summarizing data. There are plenty of libraries that implement the algorithm in Javascript, R and more. While I’ve been working on an implementation with some interesting properties, this article is about understanding the alg
The Module Pattern, A Little More Detail
Once you’ve read this, read the update which has more detailed information about the module pattern’s performance profile! This is an article on the module pattern for Javascript, and some of its neat properties when used for instances. I’ve been using it recently for projects like mapbox.js, and think it’s a neat way to structure code and avoid some of the less likable parts of the language. For
Javascript Module Pattern, Memory, Closures
An update to Module Pattern, A Little More Detail, an article in which I first explained the idea of using closure’d objects as an alternative to Javascript’s new and prototype system objects. It’s been a few months since my first article on the Javascript module pattern and I’ve learned and read a lot, thanks to whizzes like mraleph and John Firebaugh. Here’s an update.
