Bank Holiday Bodge: A Wall of Music

Sometimes, perfection overkill. In this spirit I would like to introduce a series of new blog posts - each installment of which being written and released on a UK bank holiday - in which I plan, build, and discuss a data science project all within the span of one day. In this maiden post, I use technqiues in dimensionality reduction and web-scrapping to produce a 'Wall of Music' based off the 2017/18 Spotify top 100 tracks.

Paradoxical Tournaments

Deciding the winner of a round-robin tournament is no simple task. The most naïve approach can easily be faltered by the existence of $k$-paradoxical tournaments. But what are these tournaments and what do we know about them? There is surprisingly little discussion on the topic and so, in this post, I plan to collate various pieces of knowledge on the subject into one succinct guide.

Integrating Hexo and Jupyter to Build a Data Science Blog

When creating a data science blog, there are many different approaches that can be taken. The main two decisions revolve around how you wish to write your content and which static site generator you wish to use to build your site. For the last year I have been using RStudio, Blogdown, and Hugo to achieve this but - after much deliberation - I have decided that change is needed. This blog post follows my transition to building a data science blog powered by Jupyter and Hexo, the obstacles I came up against, and the solutions I came to employ.

Generating Normal Random Variables - Part 1: Inverse Transform Sampling

The normal distribution is one of the most important developments in the history of statistics. As well as its useful statistical properties, it is so well-loved for its omnipresence in the natural world, appearing in all sorts of contexts from epidemiology to quantum mechanics. This blog post, the first in a series of posts discussing how we can generate random normal variables, explores the theory behind and the implementation of inverse transform sampling.

Efficiently Solving a Google Coding Interview Question Using Pure Mathematics

Pure mathematics can get a bad reputation at times for being too abstract, and losing relevance to the real world. I think this reputation is largely unjustified and so, in this post, I show how a knowledge of the pure mathematical topics of linear algebra and combinatorics led me to a blazingly fast, and devilishly simple solution to a Google coding interview question.

A Statistican's Guide to Playing Darts

Although the game of darts requires a tremendous amount of skill to be a good player, there is still a very large probabilistic element. In this post, we take undertake a stochastic analysis of the game in order to reach an optimum strategy for play depending on the typical accuarcy of your shots.

The Inaccuracy of Accuracy

In a data-driven world, your analyses will only ever be as good as the metric you use to evaluate them. In this post, I make the claim that the de facto metric used in data science is unfit for purpose and and can lead to the construction of unethical models. If this is the case, what should we use instead?

Letter Distributions in the English Language and Their Relations

If you've ever tried to solve a simple cryptography problem, then you may have developed an intuitive sense of where you're most likely to find a letter in a word. For example, 'Q's are rarely at the ends of words whereas 'D's are much more likely to be found there. This post explores this idea and concludes by clustering the letters of the Latin alphabet based on their distributions throughout English words.

Solving Complex Coverage Problems Using Microsoft Excel

Microsoft Excel is an incredibly powerful and easy to use tool for data analysis and OR. In this post, I introduce a highly generalised and complex coverage problem and walk through my solving process; from formulation, to model-building.

Creating a Dynamic 8-Bit Wallpaper for Linux with Python

Your desktop wallpaper may be the one image that you see most often in a given day so its probably worth your time to make it look the best it can. In this post, I offer a template for a dynmically-changing 8-Bit wallpaper which automatically syncs itself to sunrise and sunset times, produced using Python and compatible with Linux.
