fastqq R package

Creating quantile quantile plots faster TLDR: This is a wrap-up of a small project I made in 2021, where I managed to speed up the creation of QQ-plots by a factor 80 in the case I was working on, ( project on Github).

Speculations on 2021

Simplifying blog

Updating the blog… I finally moved back to Iceland, and I will probably have some more time to jot down what goes through my mind. I recently started a new position as a research scientist at deCODE genetics, so expect some new posts about genetics and statistics!

Part 2: Deep Learning with Closures in R

Let’s go on! If you just arrived, you can check out the first part here. The goal of this series is to demonstrate how compactly we can implement an MLP in a functional programming paradigm and how easy it becomes to extend/play around with it.

Part 1: Deep Learning with Closures in R

Start of a small series The gif below is the evolution of the weights from a neural network trained on the mnist dataset. Mnist is a dataset of handwritten digits, and is kind of the hello world/FizzBuzz of machine learning.

Visualizing Strange Attractors

What is a strange attractor? The wikipedia article on attractors gives the following definition/explanation: An attractor is called strange if it has a fractal structure. This is often the case when the dynamics on it are chaotic, but strange nonchaotic attractors also exist.
