Katherine Heller
I am currently an EPSRC Postdoctoral Research Fellow at the
University of Cambridge .
I am also a visiting researcher at the
Gatsby Computational Neuroscience Unit .
In general my research interests lie in the area of machine learning. More
specifically, I am interested in Bayesian statistics, clustering,
information retrieval, and semi-supervised learning. I have also done research which
applies machine learning techniques to problems in computational biology,
computer security, and computer vision.
I am co-organizing a NIPS 2009 workshop on
