# Regularisation

Here’s a post which combines my favourite bits of writing a blog – fairly mathematical, not too simple or difficult to implement, mostly based around pictures, not covered in my undergraduate education, and pretty damn useful in my job. Excited? You should be.

# England and Wales House Prices

The last time I looked at house prices it went pretty well, and I ended up winning a data science competition. There I was only dealing with a million or so records, and a relatively small 120 MB dataset. Then I found out it was possible to download 3.7GB of property sale records for all of England and Wales since 1995, so let’s have another go. Continue reading

# Stop the bus

Holidays are so relaxing. You know the drill: lounge around, eat and drink haphazardly, play card games, simulate several million card games to gain an advantage over your opponents, go for walks, visit the seaside, derive relationships for expected values of card hands, buy chocolates, smash unsuspecting opponents through brute force, send a postcard, etc. etc.

# Lens Lab Matlab App

Given a few of my previous posts it’s obvious that I’m a fan of the physics and mathematics that that comes along with the theory of classical optics. To make the number of lens-based posts a nice round three then, here’s a simple Matlab App I made over the last few days which lets you play with lenses interactively, hopefully giving a bit of useful insight into the underlying principles.

# Fourier Vases

In my last blog post I waded through a lot of maths with no pretty pictures to show for it. I’ll redress the balance here and make the pictures extra pretty. The post title alludes to a previous post, and is similar in that I’ll be using mathematics to form interesting 3D objects.

# Bus-teresis

What does this title mean? What’s with the recent bus obsession? Is this post even about buses, or are they just being carelessly shoehorned into every post title from here on out? Excellent questions, thanks for asking. Allow me to explain.

# A New Perspective

I was playing pool recently, rather badly, and remembered it was much easier to play on a computer, when one can look down on the table from above and see where the balls are more easily. Wouldn’t it be great if there was a way to see this in real time when playing pool? I haven’t done that here, yet, but lets have a look at the steps which might be involved in a solution.
