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 …
Predicting the Future
One of the most well known examples of using Gaussian Process Modelling for forward prediction is the application described in Rasmussen & Williams, which shows the prediction for the future of atmospheric CO2 levels. When the book was written, the prediction showed the increase in CO2 concentration continuing at roughly the same rate. However, things …
Furrier Cats
Last week I gave an introductory lecture on imaging with radio interferometers. I started off with a Python demonstration of Fourier filtering using cat pictures, which seemed pretty popular and lead to one of my fellow lecturers coining the term "Furrier Cats" (this is genius and I wish I'd thought of it). Since it was …
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 …
