Hi!

I am a final year PhD student in the Machine Learning and Optimisation Research Group in the School of Computer Science at The University of Manchester. I work under the supervision of Magnus Rattray.


My research interests include many aspects of machine learning and computational biology. I am particularly interested in all aspects of Bayesian inference including the development of improved approximate inference algorithms.


However, the particular focus of my PhD project has been on inference in sparse factor analysis models, motivated by the problem of trying to infer simple models of transcription networks.


A copy of my current Curriculum Vitae can be found here.


I am grateful to receive funding from an EPSRC PhD scholarship and a PhD scholarship supported by Manchester alumni through Your Manchester Fund.

Code

Matlab code implementing the Dense Message Passing algorithm described in the AIStats 2010 paper mentioned above is available here (32KB).


This download includes everything required to reproduce the results in the paper for the dense message passing algorithm applied to synthetic data. Please see the README.txt file within the download for instructions.

To reproduce the gene expression data results and the results for the other algorithms you will also need to download data and code from the appropriate websites. Please see the README.txt file within the download for instructions about how to obtain these.

If you have any problems, please email me. I will be happy to help.
