Its latest iteration, Fortran 2023 is a modern language by today’s standards. However, its very first version, released in 1956, is rather simple, containing only a small set of commands. To get a feel for what it was like, I'll walk through a FizzBuzz implementation in this post. Let's start with the code: c FizzBuzz program in FORTRAN 1 1… ## [PCA for Classification Is as Bad as Random](https://blog.fugue88.ws/archives/2024-11/PCA-for-Classification-Is-as-Bad-as-Random) _2024-11-27 · David Owen · David Owen’s blog_ Basically, PCA (Principle Component Analysis) finds projection axes based on total population variance. Because that is not correlated with classes, that means that adding PCA into your classification pipeline is essentially adding a random variable. Or, more exactly, it's like using a set of random, orthogonal projection axes. Here's a simple example of PCA making classification harder……
