Who am I?

I graduated from Churchill College in 1998 with a BA and MSci in Natural Sciences.

I completed my PhD with the Inference Group in 2001.

I now work at Spiral Software in Cambridge.


Research

Human-Computer-Interaction

Dasher   is a text entry interface currently under development. It uses a PPM compression algorithm as a basis for language modelling. I've presented a paper on Dasher at UIST 2000. See below for the postscript.
 

Language Modelling

I have developed the Dirichlet Language Model to reduce redundancy.

I have been working on Restricted Boltzmann machines as language models. These are inspired by Geoff Hinton's Product of Experts learning algorithm.

I have also developed Neural Networks as language models. On toy problems, these outperform PPM, the state-of-the art text compression algorithm.

Papers



Neural Networks

My recent talk on Modelling Discrete with Neural Neworks demonstrated PPM-beating models.

Eye-tracking

Hardware

We have an eye-tracker from EyeTech Digital Systems. It consists of two infra-red emitters, and a camera which plugs into the back of a PC.

Software

MS Windows

The system as supplied with software which works on Windows.

Linux

The infra-red camera is connected to a PCX framegrabber, manufactured by Imagenation. They have supply PXC drivers for both Windows and Linux.

Dasher

Dasher is a data-entry inteface which can be used with an eyetracker.
