I'm a professor in the Machine Learning Group of the Computational and Biological Learning Lab in the Division of Information Engineering at the Department of Engineering in Cambridge.


I have very broad interests in probabilistic inference in machine learning, covering both unsupervised, supervised and reinforcement learning. I'm particularly interested in design and evaluation of non-parametric methods such as Gaussian processes and Dirichlet processes. Exact inference in these models is often intractable, so one needs to resort to approximation methods, such as variational techniques or Markov chain Monte Carlo.

Gaussian Processes

I have co-authored a book with Chris Williams, entitled Gaussian Processes for Machine Learning, MIT Press, 2006, online version. Gaussian processes are a principled, practical, probabilistic approach to learning in kernel machines. The book describes Gaussian process approaches to regression and classification. It also discusses methods for hyperparameter tuning and model selection. Detailed algorithms are given, and demonstrations and a matlab implementation allowing very general covariance structures are available at the book web site. I gave a tutorial lecture on Gaussian processes at the NIPS 2006 conference. I also maintain a web site on Gaussian processes. Gaussian Processes for Machine Learning cover

Reinforcement Learning

I'm interested in how to speed up reinforcement learning by using a model-based approach with probabilistic models. See a short demo.
