Stars spin - and the rate at which they spin has a profound affect on their health. So measuring the rotation of different types of stars is an important pass-time for astronomers who like that kind of thing (i.e. stars). Fortunately stellar rotation is something that can even be measured directly from their time dependent …
Gaussian Process Modelling in Python
Non-linear regression is pretty central to a lot of machine learning applications. However, when you don't know enough/anything about the actual physical parametric dependencies of a function it can be a bit of a show-stopper. But... what if you could predict the value of a function at any point based only on its value at …
Gaussian Processes in Python
I'm guessing that most people are pretty comfortable with the concept of uncorrelated Gaussian noise. It's the most frequently assumed noise. Even if you don't realise it, you're probably assuming Gaussian noise. Quick check: Are you using a chi-squared test to fit your data? Yes? Well there you go. Co-variate Gaussian Noise Here I'm going …
