I am James Murphy, a Research Associate in the Signal Processing group in Cambridge University’s Department of Engineering. My academic interests lie primarily in computational statistics, machine learning and information retrieval. In particular I am interested in estimation of network structures between multiple time series. I also have a long-standing interest in software development across various languages and platforms.
I find science, maths and technology inspirational. They are arguably our greatest collective project and to play even the smallest role in that is a great thing. This website is a place for me to collect some of the work that I have done over the past few years and share it with a wider audience. I hope that some of this content is useful to you.
The image at the top of the site is a detail from the output of some nonlinear tracking work I did during my PhD, using Particle MCMC to learn unknown, nonparametric linkages between the tracked objects.
