Artificial Intelligence Group

The work of the Artificial Intelligence Group is multi-disciplinary, spanning genomics and bio-informatics, computational learning theory, computer vision, and informal reasoning. A unifying theme is understanding multi-scale pattern recognition problems, seeking powerful (often statistical) algorithms for modeling and solving them, and for learning from data. The AI Group seeks to find synergies amongst ideas based in statistics, mechanised reasoning, cognitive science, biology, and engineering, and to develop practical applications from them.

Members of the AI Group engaging with the final position of the famous chess match between IBM Deep Blue and world champion Gary Kasparov. In that chess game the world changed: Artificial Intelligence finally delivered on a long-awaited promise and earned its name.

John Daugman

John Daugman John Daugman is Professor of Computer Vision and Pattern Recognition in the Computer Laboratory. He obtained his AB and PhD degrees from Harvard University in the USA, where he also then taught on the Faculty. Before coming to Cambridge he held the Toshiba Chair at the Tokyo Institute of Technology, Japan, and during 2002–2004 he was the Johann Bernoulli Professor of Mathematics and Informatics at the University of Groningen, The Netherlands. He is a Fellow of the Institute of Mathematics and its Applications, and a Fellow of the International Association for Pattern Recognition. In 2013, Daugman was inducted into the US National Inventors Hall of Fame.

At Cambridge he currently teaches Computer Vision, Information Theory, and Mathematical Methods for Computer Science.

Research interests: computer vision, statistical pattern recognition, information theory and wavelets.

One outgrowth of his work has been iris recognition, an automatic and fast method for determining personal identity with very high confidence, by mathematical analysis of the random patterns that are visible in the iris of a person's eye from some distance. Professor Daugman's algorithms are the basis of all currently deployed iris recognition systems and have been licensed internationally, particularly for use in airports where governments (including the UK) allow the process to substitute for a passport. Currently the Government of India is using these algorithms to enroll and cross-compare the iris patterns of all 1.2 billion citizens of India in a national entitlements and benefits ID system. With 600 million persons enrolled so far and a further 1 million each day, some 600 trillion iris comparisons for ID de-duplication in India are performed every day with these algorithms.

(Professor Daugman is currently unavailable to supervise PhD students.)
