Tracking 3D Printing News the Emerging 3D Printing Revolution! War on 3D Printed Guns “DEFCAD files are being removed from public access at the request of the US Department of Defense Trade Controls. Until further notice, the United States government claims control of the information.” That’s the notice on Cody Wilson’s DEFCAD website, a self-proclaimed “makeshift response” that was created when M
You don't need to know anything about category theory to use Haskell as a programming language. But if you want to understand the theory behind Haskell or contribute to its development, some familiarity with category theory is a prerequisite.Category theory is very easy at the beginning. I was able to explain what a category is to my 10-year old son. But the learning curve gets steeper and steeper
In this post, we’re going to look at how to manipulate multivariate distributions in Haskell’s HLearn library. There are many ways to represent multivariate distributions, but we’ll use a technique called Markov networks. These networks have the algebraic structure called a monoid (and group and vector space), and training them is a homomorphism. Despite the scary names, these mathematical struc
