Chris J. Maddison
I am a DPhil student of statistics at the University of Oxford supervised by Yee Whye Teh and Arnaud Doucet. I also spend two days a week as a Research Scientist at DeepMind. Previously, I received my MSc. from the University of Toronto supervised by Geoffrey Hinton. I was one of the primary contributors to the AlphaGo project. My research interests are probabilistic inference and Monte Carlo methods. My other interests include neural networks, learning in non-human animals, and probability theory.

- I've started a blog, hoping to cover topics in machine learning and statistics with a focus on cool tricks and forgotten papers.
- Perturbation, Optimization, and Statistics is out! It includes with a chapter of mine, A Poisson process model for Monte Carlo, which explains the Gumbel-Max trick and Gumbel processes through the theory of Poisson processes.
- A new distribution on the simplex applied to training discrete units in neural nets: [arxiv].
- I've moved to Oxford!
