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).

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.
